[mscorlib] Ensure monotouch[_runtime] API are identical (#14665)

* [mscorlib] Ensure monotouch[_runtime] API are identical

Ensure the API surface for `mscorlib.Core.dll` is identical between the
`monotouch` and `monotouch_runtime` (used for REPL and the interpreter).

This ensure code compiled against one will be fine when building against
the other (e.g. avoiding linker errors).

In practice this means:

1. Expose the API needed for `System.Reflection.Emit` in XI

	- throwing `PlatformNotSupportedException` **by default**; or
	- calling the mono runtime when the interpreter is enabled;

2. Do not expose additional, not supported, API (e.g. COM related)

	- `monotouch_runtime` configuration was built without `FULL_AOT_RUNTIME`
	  and that brings some other stuff that is not AOT related

Follow up to #14606
