[luafilesystem] Add cmake files (#38425)

One of two ports for #38340

- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- ~[ ] SHA512s are updated for each updated download.~
- ~[ ] The "supports" clause reflects platforms that may be fixed by
this new version.~
- ~[ ] Any fixed [CI
baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt)
entries are removed from that file.~
- ~[ ] Any patches that are no longer applied are deleted from the
port's directory.~
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is added to each modified port's versions file.
