Brian Salomon 87ae989569 Revert "Threaded generation of software paths"
This reverts commit 76323bc061.

Reason for revert: Breaking NUC bots in threaded gm comparison:

Original change's description:
> Threaded generation of software paths
> 
> All information needed by the thread is captured by the prepare
> callback object, the lambda captures a pointer to that, and does the
> mask render. Once it's done, it signals the semaphore (also owned by the
> callback). The callback defers the semaphore wait even longer (into the
> ASAP upload), so the odds of waiting for the thread are REALLY low.
> 
> Also did a bunch of cleanup along the way, and put in some trace markers
> so we can monitor how well this is working.
> 
> Traces of a GM that includes GPU and SW path rendering (path-reverse):
>

> Threaded, with wait in the callback (notice pre flush callback blocking):

> Current version, with wait deferred to ASAP upload function:
