 WPDB: Always use `mysqli` when available.

 This change makes WordPress use `mysqli` on PHP <5.5 when available,
 instead of only in PHP 5.5+ and development installs.

 WPDB includes a fallback to `mysql` in the event that the database
 connection fails with `mysqli` so incompatibilities should be few and far
 between.

 Fixes #42812 for trunk.
