* Fix introspection failures (due to [breaking] changes)
* [tests][intro] Fix hang for tvOS
Creating an instance of `NSMetadataQuery` hangs the simulator.
Even after (xharness) timeout the simulator is not in a good state
to run further tests and every new (tvOS) test will also hang...
* [tests][intro] Same hang for watchOS
except that further test execution does not seem affected (like tvOS)

* Bump system mono to the latest available 2020-02 package. (#10402)
This makes xamarin-macios build on Apple Silicon, and also seems to get an
updated csc that fixes a problem with nullability warnings/errors.
* [tests] Fix mmp-regression build

This happens on BigSur as it does not find the default location anymore...
* [tests] Do not test GKLeaderboardViewController on BigSur
The issue is the OS version, not the Xcode version. Update check
to skip that test on macOS 11+
* [tests] Fix MSBuild tests / integration
The test cannot work on BigSur since while you can `dlopen` the library
you can open `fopen` it as a file (and can't embed it for the test).

```
* [tests] Fix MTouch tests failures
* `nm` changed it's output and test was updated
* `clang` linking has a much higher limit for it's command-line length
At least it does not seem to be OS specific since both 10.15 and 11.0
returns the same maximum

```
* [xcode12] Bump to Xcode 12 Beta 4
* [Tests] Disable Trust_FullChain and Trust2_FullChain tests
These tests started showing a different error than the one we expect
I'll let our security expert chime in
