[nfarid]

The cmake options that TGUI uses has changed:
https://github.com/texus/TGUI/blob/2aaacf812d71d0856c54df32cc3c5e375f742e59/src/Backend/CMakeLists.txt https://tgui.eu/tutorials/latest-stable/backends/

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.
