Generate CI scripts as powershell on Windows. This is intended to
output exactly the same bash scripts as before on Linux.

Running a `spack-python` script like this:
```python
import spack
import multiprocessing
def echo(args):
print(args)
if __name__ == "__main__":
pool = multiprocessing.Pool(2)
pool.map(echo, range(10))
```
will fail in `develop` with an error like this:
```console
_pickle.PicklingError: Can't pickle <function echo at 0x104865820>: attribute lookup echo on __main__ failed
```
Python expects to be able to look up the method `echo` in `sys.path["__main__"]` in
subprocesses spawned by `multiprocessing`, but because we use `InteractiveConsole` to
run `spack python`, the executed file isn't considered to be the `__main__` module, and
lookups in subprocesses fail. We tried to fake this by setting `__name__` to `__main__`
in the `spack python` command, but that doesn't fix the fact that no `__main__` module
exists.
Another annoyance with `InteractiveConsole` is that `__file__` is not defined in the
main script scope, so you can't use it in your scripts.
We can use the [runpy.run_path()](https://docs.python.org/3/library/runpy.html#runpy.run_path) function,
which has been around since Python 3.2, to fix this.
- [x] Use `runpy` module to launch non-interactive `spack python` invocations
- [x] Only use `InteractiveConsole` for interactive `spack python`
Often in containers, the files we use to detect whether a cray system supports new features are not available.
Given that the cray containers only support the newer versions, and that these versions have been
around for a while at this point and few sites don't support them, this PR changes the logic for
detecting cray systems so that:
1. Don't even consider whether something is the `cray` platform if `opt/cray` is not in `MODULEPATH`
2. Only use the `cray` platform if we can read files in /opt/cray/pe and positively detect an older version
3. Otherwise, assume we're *not* on a cray (includes newer Cray PE's, which we treat as Linux)
`jinja2` can be a costly import, and right now it happens at startup every time we run
Spack. This slows down `spack --print-shell-vars` a bit, which is needed by `setup-env.*sh`.
Patch allowing Clingo to build with VS22 has landed both in Spack
and Clingo upstream, update Spack's bootstrap constraints to handle
this.
Additionally, properly scope the patch application in the clingo
package to handle upstream patch.
Currently (outside of this PR) when you `spack develop` a path, this path is treated as the staging
directory (this means that for example all build artifacts are placed in the develop path).
This PR creates a separate staging directory for all `spack develop`ed builds. It looks like
```
# the stage root
/the-stage-root-for-all-spack-builds/
spack-stage-<hash>
# Spack packages inheriting CMakePackage put their build artifacts here
spack-build-<hash>/
```
Unlike non-develop builds, there is no `spack-src` directory, `source_path` is the provided `dev_path`.
Instead, separately, in the `dev_path`, we have:
```
/dev/path/for/foo/
build-{arch}-<hash> -> /the-stage-root-for-all-spack-builds/spack-stage-<hash>/
```
The main benefit of this is that build artifacts for out-of-source builds that are relative to
`Stage.path` are easily identified (and you can delete them with `spack clean`).
Other behavior added here:
- [x] A symlink is made from the `dev_path` to the stage directory. This symlink name incorporates
spec details, so that multiple Spack environments that develop the same path will not conflict
with one another
- [x] `spack cd` and `spack location` have added a `-c` shorthand for `--source-dir`
Spack builds can still change the develop path (in particular to keep track of applied patches),
and for in-source builds, this doesn't change much (although logs would not be written into
the develop path). Packages inheriting from `CMakePackage` should get this benefit
automatically though.
The `patch()` directive can now be invoked with `reverse=True` to apply a patch in reverse.
This is useful for reverting commits that caused errors in projects, even if only the forward
patch is available, e.g. via a GitHub commit patch URL.
`patch(..., reverse=True)` runs `patch -R` behind the scenes. This is a POSIX option so we
can expect it to be available on the `patch` command.

fixes#43097
Before this PR the behavior of mixins used together with
builders was to mask completely the callbacks defined from
the class coming later in the MRO.
Here we fix the behavior by accumulating all callbacks,
and de-duplicating them later.
Remove dependency on `importlib_metadata` and `pkg_resources`, which can be problematic if the version in PYTHONPATH is incompatible with the interpreter Spack is running under.
Closes#43052.
Maybe moving the argument to the `find` subcommand is a good idea, but I
just wanted to get the docs fix out.

This PR adds the ability to load spack extensions through `importlib.metadata` entry
points, in addition to the regular configuration variable.
It requires Python 3.8 or greater to be properly supported.
* ASP-based solver: improve reusing nodes with gcc-runtime
This PR skips emitting dependency constraints on "gcc-runtime",
for concrete specs that are considered for reuse.
Instead, an appropriate version of gcc-runtime is recomputed
considering also the concrete nodes from reused specs.
This ensures that root nodes in a DAG have always a runtime
that is at a version greater or equal than their dependencies.
* Add unit-test for view with multiple runtimes
* Select latest version of runtimes in views
* Construct result keeping track of latest
* Keep ordering stable, just in case
* Execute `args.help` after setting main options so that extension commands will show with `spack -h`

Spack merges ranges and concrete versions if they have non-empty
intersection. That is not enough for adjacent version ranges.
This commit ensures that disjoint ranges in version lists are simplified
if their union is not disjoint:
```python
"@1.0:2.0,2.1,2.2:3,4:6" # simplifies to "@1.0:6"
```
Refactoring `SpackSolverSetup` is a bit easier with type annotations, so I started
adding some. This adds annotations for the (many) instance variables on
`SpackSolverSetup` as well as a few other places.
This also refactors `condition()` to reduce redundancy and to allow
`_get_condition_id()` to be called independently of the larger condition
function.

Some builds on Windows break when encountering paths with spaces. This
reencodes some paths in Windows 8.3 filename format (when on Windows):
this serves as an equivalent identifier for the file, but in a form that
does not have spaces.
8.3 filenames are also truncated in length, which could be helpful, but
that is not the primary intended purpose of using this format.
Overall
* nmake/msbuild packages do this generally for the install prefix
* curl/perl require additional modifications (as written now, each package
may require calls to `windows_sfn` to work when the Spack
root/install/staging prefixes contain spaces)
Some items for follow-up:
* Spack itself does not create paths with spaces "on top" of whatever
the user configures or where it is placed (e.g. the Spack root, the
staging directory, etc.), so it might be possible to edit some of these
paths once and avoid a proliferation of individual `windows_sfn`
calls in individual packages.
* This approach may result in the insertion of 8.3-style paths into
build artifacts (on Windows), handling this may require additional
bookkeeping (e.g. when relocating).
* Move spec_list into its own file, instead of __init__.py
* Remove spack.schema.spack
This module was introduced in #33960 It's almost an exact duplicate of
spack.schema.env, and is not used anywhere.
* Fix typo
