Philip Elcan f180ad0199 gpu: nvgpu: gr: use enum for global_ctx_buffer_index ...

Change the global_ctx_buffer_index member in the nvgpu_gr_ctx struct
to be an enum nvgpu_gr_global_ctx_index. global_ctx_buffer_index is
used as an array of these indicies, but had been declared as an int.
This change resolves a number of MISRA Rule 10.3 violations for implicit
assignment of objects of different essential or narrower type.

In order to use this enum, it is moved out of global_ctx.h into a new
header file ctx_common.h that can be used by both ctx.h and global_ctx.h.
