Updates for sst 14.1.0

[kpgriesser]

These edits are intended to merge after SST 14.1.0 is available.
This branch was tested using set-core version:
commit 7848d804fbdb0f936736f36b67f8f636547fd7f9 (HEAD -> master, origin/master, origin/HEAD) Merge: 0d412e16 1cc35cc8 Author: SST AutoTester <[email protected]> Date: Thu Oct 3 08:07:23 2024 -0600

Changes:

• changed checkpoint restore tests to use new directory structure containing checkpoint files.
• added wrapper script, sst-chkpt.sh, to remove previously generated checkpoint directory before running sst with checkpoint. This way the new checkpoint data always goes to the same directory.
• added SCRIPT variable for CMakeLists.txt to refer to scripts directory.
• Modified all test CMakeLists.txt files for tests that generate checkpoints to use the wrapper script to remove the checkpoint directory first.
• changed sst-major-version.sh to allow for '-dev' versions of sst. These will always be assumed to be current. ( sst development versions do not appear to have numbering... just '-dev')
• Fixed a typo in large-stat-chkpnt.cc preventing compilation.
• commented out large-stat-chkpnt tests in test/CMakeLists.txt. These are timing out and filling the disk.

Only concerns are whether the large-stat tests were working with sst 14.0. Since the code didn't compile I assumed this was a work in progress. I only ran them with the latest master branch for sst-core.

Expecting sst-core to change again before it is released so no point in merging this to devel just yet.

large-stat-chkpnt shouldn't compile until SST 14.1.0. This should be disabled by default until the build system detects 14.1.0+. large-stat should build and run fine.

I've put back in the large-stat* tests but there are timing out and generating some really large files.
Other than that, this PR is tested on MacOS and Ubuntu using the 14.1.0_beta branches for sst-core and sst-elements. Ready for your review for merging.
