* [runtime] Mark numerous Mono Embedding API as used only by the MonoVM bridge.
* [runtime] Exclude more unused code from the CoreCLR build.
* There's no tracing in CoreCLR, so no need to process the MONO_TRACE environment
variable (and set the trace options).
* There's no sdb debuggger, so that code can be skipped.
* The profiler support is very different, so skip that code too.
* We don't support AOT, nor aot data files, so skip that.
* [runtime] Stop generating dummy implementations of the Mono Embedding API for CoreCLR.
All of the Mono Embedding API now falls in either of these two categories:
* Only used by the MonoVM bridge.
* Has a CoreCLR implementation.
Which means that we don't need the code to generate dummy implementations for
methods that aren't in any of these two categories anymore.
The implementation will be completely different, where the hook into CoreCLR
is in managed code.
We still need to initialize the framework_peer_release_lock mutex, so move
that code out of gc_enable_new_refcount.
We need to call coreclr_initialize/monovm_initialize at startup, so do that.
This is a partial implementation, in that we're not setting all the properties
that we should, and also the PINVOKE_OVERRIDE callback is not doing everything
it should either yet.

* [runtime] Link the coreclr version of libxamarin with CoreCLR instead of Mono.
The diff might look a bit weird, because there's no changes specific to CoreCLR -
the difference is that we're in fact removing a special-case to link with Mono: we
used the DOTNET_$(rid)_LIBDIR variable to specify the directory where to find libcoreclr,
we now use DOTNET_CORECLR_$(rid)_LIBDIR when building for CoreCLR, but that's handled
by the default case, so no need to add any special casing. We still override DOTNET_osx-<arch>_LIBDIR
for MonoVM (no change needed for that).
* [runtime] Generate stubs for the mono embedding API when building for CoreCLR.
This makes libxamarin link successfully when building for CoreCLR.
* [runtime] Clean up public symbols. Fixes#5124.
Clean up public symbols, by:
* Symbols that don't need to be public (most of them), can be private.
* Prefix all public symbols with `xamarin_`.
* Add a test to ensure we don't introduce new public symbols.
* Use C symbols instead of mangled C++ symbols, since those are easier to
handle in the test.
This minimizes the chance of getting into a symbol clash with another native library.
Fixes https://github.com/xamarin/xamarin-macios/issues/5124.
* Some test fixes.
This makes exception marshaling work with Xamarin.Mac apps that use the system
mono (such as Visual Studio for Mac, and assuming at least a v5.12 system
mono).

mono_set_pending_exception is a private mono symbol, which means we won't find
it when using the system mono (as a dynamic library). In that case, we'd
abort.
Instead try to call mono_raise_exception, and hope for the best. It will leak
somewhat, but that's still better than asserting.
This changes the generated wrapper function from:
```c
MONO_API void
mono_set_pending_exception (MonoException * exc)
{
if (mono_set_pending_exception_func == NULL)
xamarin_assertion_message ("Could not load mono_set_pending_exception\n");
return mono_set_pending_exception_func (exc);
}
```
to
```c
MONO_API void
mono_set_pending_exception (MonoException * exc)
{
if (mono_set_pending_exception_func == NULL)
return mono_raise_exception (exc);
return mono_set_pending_exception_func (exc);
}
```
Also this only applies to Xamarin.Mac apps that use the system mono (such as VSfM).
https://bugzilla.xamarin.com/show_bug.cgi?id=59979
The two functions mono_class_is_nullable and mono_class_get_nullable_param are
private mono symbols, which means we can't call them when using Xamarin.Mac
with libmono from a dynamic library.
Implement a fallback for this case, where we call a managed method when these
functions are not available (and restrict this workaround to Xamarin.Mac only,
since it's not needed for Xamarin.iOS).
* [runtime] Use printf on watchOS, NSLog doesn't shown up (by default).
* [runtime] Use a wrapper function for logging.
So that we can chose between printf and NSLog at runtime,
depending on where we're running.
