gpu: nvgpu: vgpu: suspend/resume contexts

Browse Source 
Add ability to suspend/resume contexts for a debug session
(NVGPU_DBG_GPU_IOCTL_SUSPEND_RESUME_CONTEXTS), in virtualized
case:
- added hal function to resume contexts.
- added vgpu support for suspend contexts, i.e. build a list
of channel ids, and send TEGRA_VGPU_CMD_SUSPEND_CONTEXTS
- added vgpu support for resume contexts, i.e. build a list
of channel ids, and send TEGRA_VGPU_CMD_RESUME_CONTEXTS
