drm/xe: Return forcewake reference type from force_wake_get_any_engine()

Adjust the signature of force_wake_get_any_engine() such that it returns
a 'struct xe_force_wake_ref' rather than a boolean success/failure.
Failure cases are now recognized by inspecting the hardware engine
returned by reference; a NULL hwe indicates that no engine's forcewake
could be obtained.

These changes will make it cleaner and easier to incorporate scope-based
cleanup in force_wake_get_any_engine()'s caller in a future patch.
