Decouple generated source plugins from SDC plugins

Some overlap with 📌 [PP-1] Refactor GeneratedFieldExplicitInputUxComponentSourceBase and FieldForComponentSuggester to need only SDC's ComponentMetadata, not SDC plugin instances Postponed here

I don't think this needs to be a stable blocker; XB at release won't yet allow additional ComponentSourceInterface implementations. Which means this would be an entirely internal refactor?

I know @mohit_aghera has a pinto component source plugin that is grappling with this so I respectfully disagree

Adding back tag until the conversation above is resolved (we can always remove it again, just want to make sure it's not lost)

Can we first do 📌 [PP-1] Refactor GeneratedFieldExplicitInputUxComponentSourceBase and FieldForComponentSuggester to need only SDC's ComponentMetadata, not SDC plugin instances Postponed , so that everything is at least using not SDC plugin instances but just \Drupal\Core\Theme\Component\ComponentMetadata?

After that, I agree the client-side schema stuff is important to generalize! Related: 📌 Evolve the organically grown `::getClientSideInfo()` into something cohesive Active .
