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.

40c9becc81 Is the query flattener restriction 29 (do not allow both EP_InnerON and 
EP_OuterON constraints on the same FROM clause term) really necessary?   This
branch explores what happens if we omit that restriction.  This is an effort
to address the performance regression reported by
[forum:/forumpost/96b9e5709cf47cda|forum post 96b9e5709cf47cda] that is caused
by flattener restriction 29.

5e8bb0aa13 An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). It runs speedtest1 approx. 15-20% faster but still 20-ish% slower than WASMFS.

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).
