The constraints-related helper functions also need to be used by other passes, so
I extracted it from Overload.h/cpp into its own file. When moving it, I converted
the enum to enum class, since it used to be nested in the TypeVariable class and
now it became a top-level declaration. Unfortunately, this breaks all the bitwise
operations, so I refactored it to use OptionSet instead of working with the enum
members directly.

(WTF::OptionSet::OptionSet):
* Source/WebGPU/WGSL/Constraints.cpp: Added.
(WGSL::satisfies):
(WGSL::satisfyOrPromote):
* Source/WebGPU/WGSL/Constraints.h: Added.
