I found the C++ runner hard to develop on, and we had stability issues and
outstanding feature needs that made me want something I felt good about
hacking on.  Thus, Rewrite It In Rust of the deqp runner.

The new runner includes:

- Skip lists don't reshuffle the test list.
- Known-flake handling without resorting to skip lists (fixing our main CI
  reliability issue on a3xx right now).
- Per-thread Vulkan shader caches should speed up VK CI runtime.
- Tracking of crashes separate from fails (so we can see progress on that
  front).
- Logging of deqp stderr spam (particularly assertion failures!) in the CI
  log.
- Integrated QPA filtering so we don't have bash perf issues for it.
- Logging of what caselist to go look at for a given error report (in red,
  so it's easier to find in your CI log).
- The code is 1/3 unit tests, and easy to extend for more coverage.
- Non-LAVA CI runs create a failures.csv in artifacts that you can check
  in as your deqp...
