It's now possible to add config on the command line with `spack -c <CONFIG_VARS> ...`, but the new `command_line` scope isn't reflected in the help output for `--scope`:
```bash
> spack help config
...
--scope {defaults,system,site,user}[/PLATFORM] or env:ENVIRONMENT
configuration scope to read/modify
...
```
This PR adds:
- A new runtime for `%oneapi` compilers, called `intel-oneapi-runtime`
- Information to both `gcc-runtime` and `intel-oneapi-runtime`, to ensure
that we don't mix compilers using different soname for either `libgfortran`
or `libifcore`
To do so, the following internal mechanisms have been implemented:
- Possibility to inject virtual dependencies from the `runtime_constraints`
callback on packages
Information has been added to `gcc-runtime` to provide the correct soname
under different conditions on its `%gcc`.
Rules injected into the solver looks like:

The default url couldn't be the one with v0.0.0-aws since spack was
replacing v0.0.0-aws with v<version_number> for example, deleting the
-aws suffix. I used the url_for_version method to specify this suffix.
This adds support for prereleases. Alpha, beta and release candidate
suffixes are ordered in the intuitive way:
```
1.2.0-alpha < 1.2.0-alpha.1 < 1.2.0-beta.2 < 1.2.0-rc.3 < 1.2.0 < 1.2.0-xyz
```
Alpha, beta and rc prereleases are defined as follows: split the version
string into components like before (on delimiters and string boundaries).
If there's a string component `alpha`, `beta` or `rc` followed by an optional
numeric component at the end, then the version is prerelease.
So `1.2.0-alpha.1 == 1.2.0alpha1 == 1.2.0.alpha1` are all the same, as usual.
The strings `alpha`, `beta` and `rc` are chosen because they match semver,
they are sufficiently long to be unambiguous, and and all contain at least
one non-hex character so distinguish them from shasum/digest type suffixes.
The comparison key is now stored as `(release_tuple, prerelease_tuple)`, so in
the above example:
```
((1,2,0),(ALPHA,)) < ((1,2,0),(ALPHA,1)) < ((1,2,0),(BETA,2)) < ((1,2,0),(RC,3)) < ((1,2,0),(FINAL,)) < ((1,2,0,"xyz"), (FINAL,))
```
The version ranges `@1.2.0:` and `@:1.1` do *not* include prereleases of
`1.2.0`.
So for packaging, if the `1.2.0alpha` and `1.2.0` versions have the same constraints on
dependencies, it's best to write
```python
depends_on("x@1:", when="@1.2.0alpha:")
```
However, `@1.2:` does include `1.2.0alpha`. This is because Spack considers
`1.2 < 1.2.0` as distinct versions, with `1.2 < 1.2.0alpha < 1.2.0` as a consequence.
Alternatively, the above `depends_on` statement can thus be written
```python
depends_on("x@1:", when="@1.2:")
```
which can be useful too. A short-hand to include prereleases, but you
can still be explicit to exclude the prerelease by specifying the patch version
number.
### Concretization
Concretization uses a different version order than `<`. Prereleases are ordered
between final releases and develop versions. That way, users should not
have to set `preferred=True` on every final release if they add just one
prerelease to a package. The concretizer is unlikely to pick a prerelease when
final releases are possible.
### Limitations
1. You can't express a range that includes all alpha release but excludes all beta
releases. Only alternative is good old repeated nines: `@:1.2.0alpha99`.
2. The Python ecosystem defaults to `a`, `b`, `rc` strings, so translation of Python versions to
Spack versions requires expansion to `alpha`, `beta`, `rc`. It's mildly annoying, because
this means we may need to compute URLs differently (not done in this commit).
### Hash
Care is taken not to break hashes of versions that do not have a prerelease
suffix.
Generate CI scripts as powershell on Windows. This is intended to
output exactly the same bash scripts as before on Linux.

As the cmake build is triggered by scikit build, the usual spack option
for enabling tests had no effect and the heavy test suite ran all the time.
Used https://github.com/scikit-build/cmake-python-distributions/issues/172#issuecomment-890322263
to implement how to pass options to the actual `cmake` build.
I also excluded some tests that failed for me on alma9 (gcc 11.4.1),
so the rest of the test suite can be run.
