Themes: Make sure get_theme_mods() always returns an array.

Browse Source 
This avoids a "Cannot access offset of type string on string" fatal error in `set_theme_mod()` on PHP 8 if the `theme_mods_$theme_slug` option has an incorrect value, e.g. an empty string instead of an array.

With this change, `set_theme_mod()` should be able to resolve the issue by saving a correct value.

Follow-up to [15736], [15739], [30672], [32629], [32632].

Props xknown.
See #51423.
