Stop implying Mac Catalyst attributes from the iOS attributes, and instead
treat Mac Catalyst like all the other platforms (not implying anything from
any other platform).
This makes our attribute logic much easier to reason about and understand.
It also required adding numerous Mac Catalyst attributes that were previously
implied. This task was way too big to do manually, so I made some changes to
Chris' mellite tool, and managed to do it quite easily with Roslyn with the
changes in this branch: https://github.com/rolfbjarne/mellite/tree/explicit-maccatalyst-attributes
This moves our current/legacy attributes to the ones added in dotnet 5 [1].
Short Forms (only in bindings)
| Old | New |
|---------------------------------------|-------------------------------------|
| [iOS (7,0)] | [SupportedOSPlatform ("ios7.0")] |
| [NoIOS] | [UnsupportedOSPlatform ("ios")] |
Long Forms
| Old | New |
|---------------------------------------|-------------------------------------|
| [Introduced (PlatformName.iOS, 7,0)] | [SupportedOSPlatform ("ios7.0")] |
| [Obsoleted (PlatformName.iOS, 12,1)] | [Obsolete (...)] |
| [Deprecated (PlatformName.iOS, 14,3)] | [UnsupportedOSPlatform ("ios14.3")] |
| [Unavailable (PlatformName.iOS)] | [UnsupportedOSPlatform ("ios")] |
Other changes
* `[SupportedOSPlatform]` and `[UnsupportedOSPlatform]` are not allowed on `interface` [2] which means they cannot be used for protocols. This is currently handled by inlining the existing attributes on all members.
* `[ObsoletedInOSPlatform]` was removed in net5 RC. This PR is now mapping the existing attributes to `[Obsolote]`, however multiple ones cannot be added so they need to be platform specific.
Remaining work (manual bindings update) tracked in https://github.com/xamarin/xamarin-macios/issues/11055
