[vcpkg] Expose alpha end-to-end versioning (#14852)
* Check for the 'versions' feature flag while installing a manifest
* Implement two-level fallback for Baselines:
  * First, fall back to current repo's baseline.json
  * Second, fall back to the ports in ports/
* Optimize checking out baseline.json via `git show`
* Detect presence of '$x-default-baseline' in the manifest and use that as the baseline commit (to be replaced by Federation functionality)
* If port_versions/x-/xyz.json is not found, fall back to ports in ports/
