[Clang] Normalize constraints before checking for satisfaction (#161671)
In the standard, constraint satisfaction checking is done on the
normalized form of a constraint.
Clang instead substitutes on the non-normalized form, which causes us to
report substitution failures in template arguments or concept ids, which
is non-conforming but unavoidable without a parameter mapping
This patch normalizes before satisfaction checking. However, we preserve
concept-id nodes in the normalized form, solely for diagnostics
purposes.
This addresses https://github.com/llvm/llvm-project/issues/61811 and
related concepts conformance bugs, ideally to make the remaining
implementation of concept template parameters easier
