gpu: nvgpu: add separate unit for perfbuf

Browse Source 
Add separate unit for perfbuf in common/perf/perfbuf.c which does not need to
include any h/w file. This unit will utilize HALs exported by
perf_*.c units for h/w accesses.
Add corresponding header file at include/nvgpu/perfbuf.h

Add new HAL gops.perfbuf with below operations :
gops.perfbuf.perfbuf_enable()
gops.perfbuf.perfbuf_disable()

Remove below debug session specific HALs
gops.dbg_session_ops.perfbuffer_enable()
gops.dbg_session_ops.perfbuffer_disable()

Delete file gv11b/dbg_gpu_gv11b.c since it is no longer needed now as it was
only including perfbuf sequence
Also remove perfbuf sequences from gk20a/dbg_gpu_gk20a.c
