gpu: nvgpu: add TSG support to channel event id

Add NVGPU_IOCTL_TSG_EVENT_ID_CTRL API for channel
event id support to TSGs

This API will accept an event_id (like BPT.INT or
BPT.PAUSE), a command to enable
the event, and return a file descriptor on which
we can raise the event (if cmd=enable)

Events generated for TSGs will reuse file
operations "gk20a_event_id_ops"

Bug 200089620
