Simplify logic by just enabling or disabling fsync as user specified
(default to off currently). Also remove the 4.1 version check, since
that version isn't actually supported in here.

The implementation for __str__ has been simplified to traverse the spec directly,
and doesn't call anymore the flat_dependencies method. Dead code has been
removed.
For configure (e.g. for hdf5) to pass, this option needs to be pulled out when invoked in ccld mode.
I thought it had fixed the issue but I still saw it after that. After some digging, my guess is that I was able
to get hdf5 to build with ifort instead of ifx. Lot of overlapping changes occurring at the time, as it were.
There are still outstanding issues building hdf5 with ifx, and Intel is looking into what appears to be a
compiler bug, but this manifests during build and is likely a separate issue.
I have verified that the making the edit in 'ccld' mode removes the -loopopt=0 and enables hdf5 to pass
configure. It should be fine to make the edit in 'ld' mode as well, but I have not tested that and didn't
include an -or- condition for it.
Add new release of SEACAS.
Update netcdf-c version to recent release which fixes some issues that have caused problems in past
Use release version of CGNS instead of develop
* Update Nalu-Wind to remove SuperLU from Trilinos requirement. Also simplify Nalu-Wind package.
* Leave boost option in nalu-wind.
* Add git branches into TPL requirements. Update OpenFAST for change to main branch.
Currently, environment views blink out of existence during the view regeneration, and are slowly built back up to their new and improved state. This is not good if other processes attempt to access the view -- they can see it in an inconsistent state.
This PR fixes makes environment view updates atomic. This requires a level of indirection (via symlink, similar to nix or guix) from the view root to the underlying implementation on the filesystem.
Now, an environment view at `/path/to/foo` is a symlink to `/path/to/._foo/<hash>`, where `<hash>` is a hash of the contents of the view. We construct the view in its content-keyed hash directory, create a new symlink to this directory, and atomically replace the symlink with one to the new view.
This PR has a couple of other benefits:
* It future-proofs environment views so that we can implement rollback.
* It ensures that we don't leave users in an inconsistent state if building a new view fails for some reason.
For background:
* there is no atomic operation in posix that allows for a non-empty directory to be replaced.
* There is an atomic `renameat2` in the linux kernel starting in version 3.15, but many filesystems don't support the system call, including NFS3 and NFS4, which makes it a poor implementation choice for an HPC tool, so we use the symlink approach that others tools like nix and guix have used successfully.
* Added the option to use high performance linkers: gold and lld, for
LBANN. Including them as build flags causes unnecessary propagation
to all dependent packages, reducing package reuse.

The ASP-based solver now accounts for the presence
in the DAG of deprecated versions and tries to minimize
their number at highest priority.
