Currently, when we hit an assertion failure, the fuzzer stops
immediately without producing a crash. This patch makes it so that we do
a hard abort instead which will be caught.

To help with Device Loss, this splits Device backend destructors

WaitForIdleForDestruction waits for GPU to finish, checks errors and gets

Destroy is used to clean up and release resources used by device,

This adds a script which runs the end2end_tests, captures a wire trace,
and then minimizes the corpus with the fuzzer. Minimizing the corpus
requires libfuzzer, so this only works in a Chromium checkout.
Unseeded, the fuzzer starts with coverage of about 600 features.
Using a seed corpus captured from the tests, the fuzzer quickly
increases coverage to about 10,000 features.
