Extensibility: Make Block Bindings work with editor.BlockEdit hook (#…

…67370) * Block Bindings: Move the place when the attributes get overriden * Fix failing unit tests * Wrap Edit with bindings logic only when the block supports it * Extend the test plugin with `editor.BlockEdit` filter * Add a new test covering the extensibility inside inspector controls * Fix the issue with missing context established by sources Co-authored-by: gziolo <[email protected]> Co-authored-by: SantosGuillamot <[email protected]>
