Themes: Clean up inactive themes' theme mods from being autoloaded as part of upcoming 6.5 upgrade routine.

Browse Source 
Alongside [57153], this reduces unnecessarily autoloaded data from inactive themes, which can contribute to slow database performance as part of excessive autoloading. This changeset specifically resolves the issue for existing sites.

Fixes #59975.
See #39537.
