[PATCH i-g-t v4 2/3] lib/xe/xe_spin: Export xe_spin_sync_wait

[Soham Purkait <soham.purkait@intel.com>]

Make function xe_spin_sync_wait() public
Which waits for the spin batch associated with the
given igt_spin object to complete by waiting
on its syncobj after spin end is executed.

v1:
 - Add simple commit message. (Kamil)
v2:
 - Add fd description for xe_spin_sync_wait. (Kamil)
 - Add improved documentation for xe_spin_sync_wait. (Kamil)
