Subject: [PATCH] Add error if a user attempts to install WordPress with
 DO_NOT_UPGRADE_GLOBAL_TABLES defined

The install process runs through migrations to global tables, therefore we cannot install WordPress with this constant defined. This error message prevents a false success screen from being seen.

Fixes #32011.
Props Oxymoron.
