976b50620a Merge opfs-wl into trunk, not so much for the "opfs-wl" VFS, which is stil tentative (working fine but with little perceived benefit), but for the "opfs" VFS cleanups which necessarily happened around it.

237fce8205 Extend the JS pre-bootstrapping configuration to include an option to disable inclusion of any given extension VFS (not the default VFSes, like memdb). The primary motivation for this is to give people who don't use OPFS to a way to keep the OPFS VFSes from loading their proxy workers, which are expensive.

ac63b524ac Add some jitter and duration info to the opfs concurrency tester. Ensure that Atomics.waitAsync() is available for opfs-wl. Further testing has shown that Web opfs-wl is consistently fairer about doling out contested locks but it's dog slow compared to the original VFS under moderate concurrency. In single-connection use they're effectively on par.

7b9cd03c0a This Web Lock impl can reliably run a single OPFS connection but rather unreliably 'loses' workers with higher counts, presumably due to deadlock or deadly embrace (how _all_ of them can deadlock at once is unclear, but clearly a bug).

cef3ff74cd The opfs-wl lock hang has been traced to starvation between the WebLock and the tight wait-on-VFS-calls Atomics.wait() loop. This can reportedly be resolved with another level of indirection in which the WebLock takes over the wait-on-VFS-calls part until it's unlocked, returning to the global loop when it's done. That exceeds this morning's ambitions but is next to try out.
