* add PopBack tests: same performance profile exactly

* use Mutex instead of Spinlock

It's safer, and so far equally performant in benchmarks of opt builds

* add deque test for comparison. It is faster on all tests.

* Add sparsely-populated multi-threaded benchmarks.

* fix

* fix

* refactor to help thread safety analysis

* Specialize WorkQueue for Closure*s and AnyInvocables

* remove unused callback storage

* add single-threaded benchmark for closure vs invocable

* sanitize

* missing include

* move bm_work_queue to microbenchmarks so it isn't exported

* s/workqueue/work_queue/g

* use nullptr instead of optionals for popped closures

* reviewer test suggestion

* private things are private

* add a work_queue fuzzer

Ran for 10 minutes @ 42 jobs @ 42 workers. Zero failures.

Checked in a selection of 100 good seeds after merging the thousands of
results.

* fix

* fix header guards

* nuke the corpora

* feedback

* sanitize

* Timestamp::Now

* fix

* fuzzers do not work on windows

* windows does not like multithreaded benchmark tests
