i915.c: Allocate Intel compressed buffers with modifiers
Before the CL, the environment variable
|ENABLE_INTEL_MEDIA_COMPRESSION| control minigbm's behaviour
to allocate the appropriate Intel media compressed buffers.
This variable is set accordingly to a feature flag in chrome
to support video decoding.
This CL removes the environment variable and will let chrome
pass the DRM specific modifier via
gbm_bo_create_with_modifiers() instead. With the modifier
passed, the CL includes the change to have the driver
compute the metadata for the compressed buffers.
BUG=b:315390307
TEST=Video playyback on chrome with MC support.
