[feature] Default to WASM-based SQLite driver (#3053)

* [feature] Default to WASM-based SQLite driver

With 0.16 out this switches our default SQLite driver to the WASM-based
solution instead. So far the driver seems to perform just as well.
Switching our default should result in it getting a bit more testing
during the 0.17 development cycle.
