Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. Rename x-sync-async.* to test-opfs-vfs.* Milestone: first successful test of OPFS without WASMFS.
