[godot-cpp] Create a new port (#37931)
Fixes #34492 - [X] Changes comply with the [maintainer guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md). - [X] The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines. - [X] Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all `find_package` calls are REQUIRED, are satisfied by `vcpkg.json`'s declared dependencies, or disabled with [CMAKE_DISABLE_FIND_PACKAGE_Xxx](https://cmake.org/cmake/help/latest/variable/CMAKE_DISABLE_FIND_PACKAGE_PackageName.html). - [X] The versioning scheme in `vcpkg.json` matches what upstream says. - [X] The license declaration in `vcpkg.json` matches what upstream says. - [X] The installed as the "copyright" file matches what upstream says. - [X] The source code of the component installed comes from an authoritative source. - [X] The generated "usage text" is accurate. See [adding-usage](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/examples/adding-usage.md) for context. - [X] The version database is fixed by rerunning `./vcpkg x-add-version --all` and committing the result. - [X] Only one version is in the new port's versions file. - [X] Only one version is added to each modified port's versions file. Notes: - This library is static only, so it's only supported for the static triplets. - Unfortunately, godot-cpp is not yet installable, so I had to patch its cmake script. I have made a PR upstream: godotengine/godot-cpp#1418 But in the meanwhile, I have created an unofficial export target `unofficial::godot::cpp`.
