gpu: nvgpu: add dynamic allowlist support

Add gv11b and tu104 HALs to get allowed  HWPM resource register ranges,
offsets, and stride meta data.

Add new enum nvgpu_pm_resource_hwpm_register_type for HWPM register
type. Add new struct nvgpu_pm_resource_register_range_map to store all
the register ranges for HWPM resources. Add pointer of map in struct
nvgpu_profiler_object along with map entry count.

Add new API nvgpu_profiler_build_regops_allowlist() to build the regops
allowlist dynamically while binding the resources. Map entry count is
received with get_pm_resource_register_range_map_entry_count() and only
those resource ranges are added for which resource is reserved by
profiler object.

Add nvgpu_profiler_destroy_regops_allowlist() to destroy the allowlist
while unbinding the resources.

Add static functions allowlist_range_search() to search a register
offset in HWPM resource ranges. Add another static function
allowlist_offset_search() to search the offset in per-resource offset
list.

Add nvgpu_profiler_validate_regops_allowlist() that accepts an offset
value, checks if it is in allowed ranges using allowlist_range_search()
and then checks if offset is in allowlist using allowlist_offset_search().

Update gops.regops.exec_regops() to receive profiler object pointer as
a parameter.

Invoke nvgpu_profiler_validate_regops_allowlist() from
validate_reg_ops() if prof pointer is not-null. This will be true only
for new profiler stack and not legacy profilers.

In gr_exec_ctx_ops(), skip regops execution if offset is invalid.
