nvc0: enable compute support on GK110:GM200 with an envvar
Without this NVF0_COMPUTE environment variable, compute support is
initialized by default and this is not what we want for now because
it might break 3D. It will be enabled by default once we are sure it
won't break anything.
Please note that compute support on GM200+ is not enabled yet because
it needs to be double-checked.
