* [mmp] Fix symbol name for 32-bit Objective-C classes. Fixes#58861.
https://bugzilla.xamarin.com/show_bug.cgi?id=58861
* [tests] Add test case for bug #58861.
https://bugzilla.xamarin.com/show_bug.cgi?id=58861
* [tests] Fix build failure for msbuild and xammac tests.
Fixes this:
> tests/common/mac/ProjectTestHelpers.cs(93,68): error CS0117: 'Driver' does not contain a definition for 'Verbosity'
* [mmptest] Fix build to build MobileBinding.dll as well.
This makes sure tests that need MobileBinding.dll actually have it.
* [mtouch] Improve how we make sure native symbols aren't stripped away. Fixes#51710 and #54417.
* Refactor required symbol collection to store more information about each
symbol (field, function, Objective-C class), and in general make the code
more straight forward.
* Implement support for generating source code that references these symbols,
and do this whenever we can't ask the native linker to keep these symbols
(when using bitcode). Additionally make it possible to do this manually, so
that the source code can be generated for non-bitcode platforms too (which
is useful if the number of symbols is enormous, in which case we might
surpass the maximum command-line length).
* Also make it possible to completely ignore native symbols, or ignore them on
a per-symbol basis. This provides a fallback for users if we get something
right and we try to preserve something that shouldn't be preserved (for
instance if it doesn't exist), and the user ends up with unfixable linker
errors.
* Don't collect Objective-C classes unless they're in an assembly with
LinkWith attributes. We don't need to preserve Objective-C classes in any
other circumstances.
* Implement everything for both Xamarin.iOS and Xamarin.Mac, and share the
code between them.
* Remove previous workaround for bug #51710, since it's no longer needed.
* Add tests.

* [mtouch] Make sure to only keep symbols from the current app when code sharing.
This fixes a build problem with the interdependent-binding-projects test when
testing in Today Extension mode.
