If unmanaged code calls QueryInterface on a CCW and that doesn't implement the requested interface we get a SIGSEGV when trying to get the GuidAttribute.

On which platforms did you notice this

[ ] macOS
[X] Linux
[ ] Windows

Version Used:
5.12/5.14

This is a regression from Mono 4.

When a class doesn't contain the desired custom attribute we used
to return the last available attribute. This prevented
`cominterop_ccw_queryinterface()` to detect that the interface
isn't implemented and lead to a crash.

This change fixes mono#10737.

The previous fix caused some memory corruption that sometimes caused
failures when trying to call icu4c methods from managed code.
Removing the HANDLE_FUNCTION_... wrapper seems to solve this.

* [tests] Renumber duplicate return codes

* [metadata] Fix crash related to custom attributes (#10737)

When a class doesn't contain the desired custom attribute we used
to return the last available attribute. This prevented
`cominterop_ccw_queryinterface()` to detect that the interface
isn't implemented and lead to a crash.

This change fixes #10737.

* [cominterop] Switch to GC Unsafe in IUnknown and IDispatch impls

These methods can be called directly from embedding APIs.
