gpu: nvgpu: handle MMU fault for TSG

- add support to handle MMU faults on a channel in TSG
- first get the ID and type of channel that engine is running
- if TSG, abort each channel in it
- if regular channel, abort that channel

- also, add two versions of API set_ctx_mmu_error(), one for
  regular channel and another for TSG
