Add sqlite3_web_vfs_list() to JS API. Corrected OPFS VFS's registering itself as the default VFS. speedtest1-worker now uses the xDelete() of both the default VFS and OPFS, to avoid that it starts up with a persistent OPFS test db (the native app calls unlink(), but that unlink call operates on a different virtual filesystem than the OPFS VFS).

Adjust speedtest1 JS build to include sqlite3-api.js so that it can use kvvfs and opfs VFSes. Permit passing of the vfs as a URL parameter to certain demo/test apps. Milestone: speedtest-worker.html?vfs=opfs runs with the standalone OPFS impl.
