Message:

Bootstrap/Load: Don't assume WP_CONTENT_DIR is defined

When the mysql extention isn't loaded and a custom db dropin is not in place, we give folks a nice error. However, we can't assume that the WP_CONTENT_DIR constant is set yet since this runs before we define default constants.

This fixes a PHP8 error.

See: #50913.
