  [clang][Basic] Add helper APIs to get language version codes from LangOptions (#163348)

Motivated by this discussion:
https://github.com/llvm/llvm-project/pull/163208#discussion_r2426842999

We will soon want to emit language version codes into debug-info.
Instead of replicating the `LangOptions -> version code` mapping we
thought we'd try to share some of the logic with the Clang frontend.

This patch teaches `LangStandard` about language versions (currently just C++ and C).
