f71c954cbc Add JS infrastructure to ostensibly allow us to customize the wasm imports, which will hypothetically allow us to eliminate the dependency on EM_JS(), but the corresponding Emscripten glue-level feature currently breaks fatally with WASMFS builds so it's disabled.

b94a98607a Rework the Emscripten-emitted module loader/init function such that it passes on the sqlite3 module, instead of the Emscripten module, to the first then() of sqlite3InitModule()'s returned Promise. This eliminates any need to mention the Emscripten module object in client-side code unless they want to configure it in advance for loading-status reports.

2897b88f9e The RIGHT JOIN logic added to version 3.39.0 added a new restriction on the 
query flattener which resulted in a performance regression for some queries,
as documented by [forum:/forumpost/96b9e5709cf47cda|forum post 96b9e5709cf47cda].
This change removes that restriction (thus restoring performance) and fixes the
problem that RIGHT JOIN was having in a different way.

0e0687ccfc 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.
