* [xtro] Add support for Mac Catalyst. Fixes #10214.
Fixes https://github.com/xamarin/xamarin-macios/issues/10214.
* Update xtro.
* Bump Objective-Sharpie.
* Delete .todo files for frameworks we don't support.
* And another one bites the dust.
* [xtro] Update.
We were using the managed name, e.g. `NSUrl`, instead of the native name,
e.g. `NSURL`, when dealing with categories.
To fix this we must resolve the type and this caused issues as other
assemblies (e.g. OpenTK) were not already loaded/cached and some type
could not be resolved (and this throw exceptions)
The runner now loads all assemblies before starting to visit them.
The fix solved a known issue (iOS-NetworkExtension.ignore), some API
that were already bound (common-Foundation.ignore) and also caught an
additional API where we missed a `[NullAllowed]` on a return value
Enabling this will ensure that future bindings (and Xcode updates that
change nullability information) are spotted right away.
The binding fixes are **not** complete, i.e. what was done was mostly
to debug the xtro rule and find corner cases. The backlog will be
_ignored_ so the builds won't fail.
* Not every old annotations have been migrated (work in progress, to be completed in another PR);
* Sanitation of the data files (e.g. removal of dupes and fixed, by Apple, entries) is done, but not automated (also a work in progress)
Even then this is immediately useful, i.e. better merged before 15.6 gets branched.
