📄 Description

Implements Neo mode differences for gnmdriver. Init sequences have a few differences, and a few command buffer writes have changed. For example, IA_MULTI_VGT_PARAM is now (conditionally) used as a uconfig register instead of context, and many draws have a bit added to the command from the flags.

All init sequences have been verified to equal that of the real gnm driver using both regular and neo modes, both with and without an extra ioctl condition passing.

Draft for now because there's still two ioctl based conditions I don't know the meaning of, currently using bool constants.
