Sync the panfrost_drm.h UAPI header with the latest from the kernel.
This adds madvise ioctl and GPU feature params.

Unless a BO has the EXECUTABLE flag, mark it as NOEXEC.

We hadn't updated the kernel header after the driver got into mainline.

This backend interacts with the new DRM driver for Midgard GPUs which is
currently in development.
When using this backend, Panfrost has roughly on-par functionality as
when using the non-DRM driver from Arm.
Alyssa Rosenzweig: To do so, we implement additional routines for
runtime GPU version detection and fencing. We cleanup some duplicate
code interfering with the new driver. We fix a long-standing memory leak
which is aggravated on the new driver. Finally, we implement BO
import/export in a way compatible with the new driver. These changes are
squashed to preserve bisectability given the hard-to-track ABI shifts in
the nondrm module
