[introspection] Fix according to macOS 12.4. Fixes xamarin#15229. (xa…

…marin#15230)

* Ignore anything Chip-related, the framework was removed from macOS.
* Fix reporting errors some protocol-related errors so that they're actually
  reported as errors (by calling 'ReportError' instead of just adding the
  errors to a list that doesn't affect anything else).
* Ignore the NSUserActivityRestoring protocol, according to the macOS headers
  it's attached to NSResponder using a category, which is invisible at
  runtime. Due to the previous point this didn't show up before, but once at
  least another error (which happened with the Chip framework), then this was
  listed as well.
* Add ignores for a couple of protocols.

Fixes xamarin#15229.
