CI: Use LLVM's OpenMP over MSVC_DEBUG_non_redist on Windows (#26678)

• CI: Use LLVM's OpenMP over MSFT_DEBUG_non_redist on Windows

Currently, we ship the non-redist debug version of microsoft's libomp. This PR changes this to official LLVM's release, also packaging the license as needed.

• Remove LLVM SHA from job name to increase legibility

• Add temp validations to CI

• Revert "Add temp validations to CI"

This reverts commit eef97c88b5bac280803ebb3c3b7bb09f89b0fd88.

• Build OpenMP in CI

• Make OpenMP fetch self-contained in cmake and cache in CI

• Robustify Licens-packaging

1. Ship OpenMP license, not LLVM's.
2. Invalidate cache also on checksum of the license

• Remove stale reference in docs/build.md

• No longer package base license in release

This was scope-creep

• Add explanatory comment to OpenMP license

• Remove arm64 smoke

Forgot this during conflict resolution during rebase of c54c0e9cf6030a5a54ce8bdd81b3e146d9787d42

• Remove GGML_OPENMP_FETCH_CACHE_DIR as requested by @CISC
