Add support for programmatic mapping and mapping configurers

[marko-bekhta]

Fixes #32760

While working on this, I noticed that imports in the analysis example were not matching the code and that one entity was missing from the analysis tests, so I adjusted that.

Also, I assumed that in this case, we would want to collect all the configurers, be it from the properties or the ones annotated with a @SearchExtension, compared to how the analysis does it (property can replace the extension configurer)
