gpu: nvgpu: gv11b: add runlist abort & remove bare channel

-Add support for aborting runlist/s. Aborting runlist/s,
 will abort all active tsgs and associated active channels
 within these active tsgs
-Bare channels are no longer supported. Remove recovery
 support for bare channels. In case there are bare
 channels, recovery will trigger runlist abort
