Run phpunit without XDebug to speed up tests

**Why:** Tests take about 8 - 9 minutes with XDebug, but closer to
3 minutes without it.

**How:** Implement strategy that mstenta@ described in https://www.drupal.org/project/farm/issues/3183687
using the dev docker image to build up the /opt/drupal directory,
but the prod image to actually run it since that image doesn't have
XDebug.
