VPR functionality is split up as static VPR and VPR resize. Static VPR
is supported on all kernels. VPR resize is enabled only on 4.9 kernel.
Enable CONFIG_NVGPU_VPR unconditionally in Linux Makefile. Compile
VPR resize related functionality in nvgpu under the check for
Linux kernel version using new define NVGPU_VPR_RESIZE_SUPPORTED.

This patch adds nvgpu API in linux and posix to query vpr resize.
The new API nvgpu_is_vpr_resize_enabled() is used in
nvgpu_submit_channel_gpfifo().
Previously, if non-deterministic channel has timeout disabled and
GPU cannot railgate on some platform, then channel doesn't power ref
count and results in video freeze. To resolve non-determinstic channel
job tracking needs to be enabled if vpr resize is supported or if GPU
can railgate.
