webgpu: Add a webgpu_traits crate (#36320)

This breaks the `script_traits` dependency  on `webgpu`. In general, the
`traits` crates shouldn't depend on Servo non-`traits` crates. This is
necessary to move "script to constellation" messages to the
`constellation_traits` crate, making it the entire API for talking to
the
constellation. This will break a circular dependency when that happens.

Testing: Successfully building is enough of a test for this one as
it is mainly moving types around.
