Put pieces in place for fiddle to support opfs, but more cleanup is required in the sqlite3.js/fiddle connection. bigIntEnabled now defaults to whether the Emscripten's module has bigint enabled. Add wasm-sensible defaults for several SQLITE_ENABLE/OMIT flags in sqlite3-wasm.c.

** At it's simplest, to build sqlite3.wasm either place this file

** -I/path flag to tell the compiler where to find both of those
** files, then compile this file. For example:
