Add new RID for Catalyst

[marek-safar]

We need to introduce new Catalyst RIDs to be able to build Catalyst runtime packs. I propose we add the following new RIDs to support them inheriting from iOS RID.

maccatalyst-arm64
maccatalyst-arm64-13
maccatalyst-arm64-14
maccatalyst-x64
maccatalyst-x64-13
maccatalyst-x64-14

I went with a simple catalyst instead of macOSCatalyst as it's very long and it runs on iPadOS as well.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

That's not the case, a Catalyst app doesn't run on iPadOS, it just supports the same APIs running on macOS and is usually used to port iPad apps to the Mac.

The official name is Mac Catalyst (see https://developer.apple.com/documentation/xcode/creating_a_mac_version_of_your_ipad_app) so I wonder if we should call the RID maccatalyst. I don't feel strongly though.

The problem with maccatalyst is that it's too long. That said, I do like it better.

While longer, it clearly states that it belongs to the Apple/Mac ecosystem. The shorter catalyst may be harder to categorize for devs not familiar with Apple.

I think maccatalyst would work too but it'd be the longest rid to have. All the existing names are much shorted (e.g. sles, tvos, ol, etc).
