Editor: Merge `uses_context` defined by block bindings sources with block types 

Adds logic that fixes the limitation for souces by allowing merging the `uses_context` defined by block bindings sources into supported block types. Each source defines the context it needs and it is added to the block types that are using the block bindings API.

Fixes #60525.
Props santosguillamot, gziolo, czapla, thekt12.
