gpu: nvgpu: prof: add new resource type

Browse Source 
Add new profiler resource type NVGPU_PROFILER_PM_RESOURCE_TYPE_PC_SAMPLER.
Introduce regops HAL get_hwpm_pc_sampler_register_ranges to get
allowlist for PC_SAMPLER resources. Re-generate allowlist files to include
register ranges for PC_SAMPLER resources.

Update uapi header to advertise new resource type
NVGPU_PROFILER_PM_RESOURCE_ARG_PC_SAMPLER.
