Convert mesa host builds to Android.bp
As this is the first conversion in this project, it sets up a new soong
namespace (to be equivalent to the logic around
BOARD_USE_CUSTOMIZED_MESA / BOARD_GPU_DRIVERS).
It also sets up a cc_defaults equivalent to Android.common.mk, and an
aosp-gen-bp.sh script that autogenerates some Android.bp files to be
used when mesa is updated.
