treat resolved symbols on RHS of module qualification as identifiers (#24180)

fixes #19866 given #23997

When searching for a module-qualified symbol, `qualifiedLookUp` tries to
obtain the raw identifier from the RHS of the dot field. However it only
does this when the RHS is either an `nkIdent` or an `nkAccQuoted` node,
not when the node is a resolved symbol or a symchoice, such as in
templates and generics when the module symbol can't be resolved yet.
Since the LHS is a module symbol when the compiler checks for this, any
resolved symbol information doesn't matter, since it has to be a member
of the module. So we now obtain the identifier from these nodes as well
as the unresolved identifier nodes.

The test is a bit niche and possibly not officially supported, but this
is likely a more general problem and I just couldn't think of another
test that would be more "proper". It's better than the error message
`'a' has no type` at least.
