Summary:
To improve the determinism of our C++ tests, I am planning to switch
TestMount to a ManualExecutor. This adds a ManualExecutor constructor
to UnboundedQueueExecutor.
In Rust, I'd use a trait, but a simple class with two constructors works fine.

Summary:
Add EdenCPUThreadPool and UnboundedQueueThreadPool types to make it clearer
that it's always okay for prefetch, deferred diff entry, and hg import to
shuttle work back to the main thread pool.
This diff changes no behavior - it just makes some invariants explicit.
