gpu: nvgpu: enable stencil zbc

Browse Source 
The implementation already exists. This change
adds NVGPU_GR_ZBC_TYPE_STENCIL and plumbs through
the stencil value from NvRmGpuDeviceZbcAddStencil
through NVGPU_GPU_IOCTL_ZBC_SET_TABLE.

Adds cases for querying the stencil values,
enabling NvRmGpuDeviceZbcGetStencilTableEntry.
