[Intel-xe] [PATCH v2 00/27] Refactor VM bind code

[Matthew Brost]

WIP on refactoring VM bind to final error handling solution.

Major changes are:
1. Allow bind / exec IOCTLs with zero binds / batches
2. Convert multiple binds from IOCTL into single job
3. CPU binds in jobs
4. Sync vs async bind per IOCTL rather than per queue

Error handling still not 100% correct but this this series structures
the code to make it possible.

This series shouldn't break any uAPI compatibility until the last patch
in the series.

v2: Rebase, Take in-syncs into account when num_execs or num_binds == 0
