dma-buf/sync_file: Add SET_DEADLINE ioctl
The initial purpose is for igt tests, but this would also be useful for
compositors that wait until close to vblank deadline to make decisions
about which frame to show.
The igt tests can be found at:
https://gitlab.freedesktop.org/robclark/igt-gpu-tools/-/commits/fence-deadline
v2: Clarify the timebase, add link to igt tests
v3: Use u64 value in ns to express deadline.
v4: More doc
