  [clang][Driver] Support simplified triple versions for config files (#111387)

Currently, the config file system loads the full target triple, e.g.
`arm64-apple-darwin23.6.0.cfg`.

This is however not very useful as this is a moving target. In the case
of macOS, that target moves every ~2 months.

We can improve this by adding fallbacks that simplify the version
component of the triple. This pull request adds support for loading
`arm64-apple-darwin23.cfg` and `arm64-apple-darwin.cfg`. See the
included test for a demonstration on how it works.
