Dion Hulse f216215864 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.
