0a42e9913b Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7].

2469350ad9 For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db.

d21d5b21db The read-only CHECK-constraint optimization of [34ddf02d3d21151b] inhibits the 
xfer optimization for tables with CHECK constraints.  However, the xfer
optimization is required for correct operation of VACUUM INTO on tables that
contain generated columns. Fix this by ignoring CHECK constraints when
qualifying the xfer optimization while running VACUUM.  Problem reported by
