devel/cdecl: Update to 5.1

Added C++20 support
Specifically, consteval functions, operator<=>(), and predefined typedefs were added: partial_ordering, strong_equality, strong_ordering, weak_equality, and weak_ordering.

Added C18 support
Since C18 is only a bugfix version, "C18" is merely recognized as a valid version of C.
