gpu: nvgpu: Add SM diversity gpu characteristic flag

Browse Source 
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute
on different hardware resources.
This feature requires a change in software to make it possible
to modify the virtual SM id to TPC mapping across mission and
redundant contexts.

This CL adds only SM diversity flags which are exposed to
its clients through ioctl/devctl interfaces.
Actual virtual SM id to TPC mapping implementation
will be part of upcoming patch sets.

Added NvGpu CFLAGS to identify the safety build
"CONFIG_NVGPU_BUILD_CONFIGURATION_IS_SAFETY"
