All the properties should be immutable and set upon exec_queue creation
using the existent extension. So, let's kill this useless and dangerous
uapi.

Mesa is the only user space component using this IOCTL, but along
with the exec_queue_create so it should be easy adoption since
it just needs to use the extension and follow the IGT examples.
A while ago on i915 Mesa team started a clean up on i915 uapi
making sure we had immutable context and buffers with all the
properties getting set at creation time. This API here now
goes against all the good clean-up work that Faith Ekstrand had
done in i915 and IGT.
So, I hope we can entirely avoid this right now.
Although only Mesa is using this IOCTL, that might impact other UMDs
since it changes the ioctl numbering.
