Widgets: Improved sidebar mapping on theme switch

Builds on efforts brought forward in #17979.

This will send sidebars through three levels of mapping:

1. If both themes have only one sidebar, that gets mapped.
2. If both themes have sidebars with the same slug, they get mapped.
3. Sidebars that (even partially) match slugs from a similar kind of sidebar will get mapped.

Finally, if the theme has previously been active and we have a record of its 
sidebar configuration then, any unmapped sidebar will be restored to its 
previous state.
