gpu: nvgpu: add HAL to insert semaphore commands

Add below new HALs
gops.fifo.add_sema_cmd() to insert HOST semaphore acquire/release methods
gops.fifo.get_sema_wait_cmd_size() to get size of acquire command buffer
gops.fifo.get_sema_incr_cmd_size() to get size of release command buffer

Separate out new API gk20a_fifo_add_sema_cmd() to implement semaphore acquire/
release sequence and set it to gops.fifo.add_sema_cmd()

Add gk20a_fifo_get_sema_wait_cmd_size() and gk20a_fifo_get_sema_incr_cmd_size()
to return respective command buffer sizes
