gpu: nvgpu: remove support for foreign sema syncfds

Browse Source 
Delete the proxy waiter for non-semaphore-backed syncfds in sema wait
path to simplify code, to remove dependencies to the sync framework (and
thus Linux) and to support upcoming refactorings. This feature has never
been used for actually foreign fences.
