Reland "[dawn][common] Adds MutexProtectedSupport CRTP wrapper."

This is a reland of commit 1e23f1ca224b164294be79b02417174f39ecfb6b

- Uses raw_ptr instead of reference in Guard because d3d11 extends
  the templates and with a reference, we lose the ability to null
  out the object to prevent destructors from running on an object
  that should otherwise have been moved.

Original change's description:
> [dawn][common] Adds MutexProtectedSupport CRTP wrapper.
>
> - Adds a CRTP wrapper that can be used to both declare a
>   MutexProtected struct and its internals. This is particularly
>   useful when we want to provide additional backdoors to read
>   data without acquiring the lock.
> - Adds relevant tests for the new wrapper.
> - Also makes Guards hold a reference instead of a pointer since
>   the pointer should never be null anyways.
