[runtime] Add some debugging aid to xamarin_release_managed_ref.

[rolfbjarne]

It's fairly frequent (due to various types of coding errors) to have the
call to '[self release]' in xamarin_release_managed_ref crash. These
crashes are typically very hard to diagnose, because it can be hard to
figure out which object caused the crash. So now we store the native
object in a static variable, so that it can be read using lldb from a core
dump.

I hope it's not a case where the handle is already nulled out at this point.

@Therzok the crash would look different if that was the case

Test failures are unrelated (https://github.com/xamarin/maccore/issues/2612).

[Therzok]

Can you please backport this to 6.x release branch?

[rolfbjarne]

@Therzok this will be included in our Xcode 14 release, which will most likely be out later this month.
