Sagar Kamble 83dbb711bb gpu: nvgpu: make buffer metadata support independent of compression ...

Earlier, buffer metadata support was made dependent on compression.
However that is not required.

Update the enabled flag NVGPU_SUPPORT_BUFFER_METADATA setup for
various hals. Enable it for all from linux characteristics init.

Update REGISTER_BUFFER and GET_BUFFER_INFO ioctls to seggregate
the compile/runtime compression functionality.

If compression is disabled, return error in case comptags are
required else don't fail the REGISTER_BUFFER ioctl.
