[vcpkg] Add `versions` feature flag and version field manifest parsing (#14079)

* [vcpkg] Add `versions` feature flag and version field manifest parsing

* Introduce FeatureFlagSettings struct to more easily access feature flags throughout the program
* To avoid users accidentally starting to write "version" instead of "version-string" in their manifests, vcpkg explicitly detects and prevents usage of ports with schemes other than "String"
* Drive-by fix of copiable SourceControlFileLocation and an exposed use-after-move bug

This code is largely extracted from PR #13777

* [vcpkg] Address CR Comments. Fix test crash on Linux.
