Daniel Rodríguez Troitiño 92652c6c95 [ClangImporter] Supporting changes towards structs with ARC pointers (#59594) ...

In order to allow supporting `__strong` (and `__weak`) struct fields,
some parts of the ClangImporter needs to understand them. The changes in
this commit allows the type importer to allow the already supported
`__unsafe_unretained` struct fields, but still reject the `__strong` and
`__weak` fields. Later changes will add support for bridging `__strong`
and `__weak` fields.

All the code should be equivalent to the previous code, and since all
the structs with non-trivial copy/destroy are completely discarded, the
code should not even be hit in any case.

The included modifications in the tests check that the error and the
diagnostics note are produced correctly.
