  [clang] fix deduction of member pointers with dependent named classes

This fixes a regression when interpreting a nested name specifier
for deduction purposes in member pointers.

This introduces a helper for fully translating a nested name specifier into a
type.

Other existing potential users will be deduplicated by using this helper
in subsequent patches.

This regression was introduced here: https://github.com/llvm/llvm-project/pull/130537
and was reported here: https://github.com/llvm/llvm-project/pull/132401#issuecomment-2751489581

No release notes, since the regression was never released.
