[c++20] For P1907R1: Add checking for structural types for non-type
template parameters.

No support for the new kinds of non-type template argument yet.

This is not entirely NFC for prior language modes: we have historically
incorrectly accepted rvalue references as the types of non-type template
parameters. Such invalid code is now rejected.
