  [clang] NFC: non-type template argument check cleanup

This is a follow-up to #134461, reverting some unnecessary changes.

This cleans up some checks around the assumption that a pack expansion
on the argument side could appear when checking non-type template arguments
when handling the pre-C++17 rules, but all of these cases are being
handled using the C++17 rules anyway.

This reverts those changes and adds an assert confirming these cases are not
possible.
