gpu: nvgpu: Add a characteristics flag to denote FECS tracing support

Browse Source 
Add a flag to nvgpu_gpu_characteristics to expose FECS tracing capability to
userspace.

This is required for adding nvrm_gpu APIs for CTXSW set of IOCTLs which were
requested in several bugs.
nvrm_gpu APIs would query this flag to check the availability of IOCTLs.
