Mac Catalyst support

[riley-usagi]

/.../SourcePackages/artifacts/TDLibFramework/TDLibFramework.xcframework:1:1: While building for Mac Catalyst, no library for this platform was found in '/.../Library/Developer/Xcode/DerivedData/ProjectName-corvnrfobakfdwcuppirqinfekkq/SourcePackages/artifacts/TDLibFramework/TDLibFramework.xcframework'.

TDLibFramework supported by individual MacOS targets.
As for Mac Catalyst, it's required for OpenSSL beeware/Python-Apple-support#117 and TDLib to support such target.

It looks like we need some patches to make it work.
PRs are welcome!
