Fix synced pattern editing in write mode and refactor block editing m…

…ode to reducer (#67026)

* Add higher order reducer for pattern block editing modes.

- Remove the prev. React effect for managing pattern block editing modes
- Implement higher order reducer in the block editor store ... it:
    - Tracks the clientIds of pattern blocks.
    - Uses the pattern block clientIds to manage block editing modes
      for pattern blocks and their inner blocks.
    - Updates both on any actions that change block lists.

* Add higher order reducer for block editing modes while section editing

* Handle RESET_ZOOM_LEVEL action

* Bug fixes

* Avoid mutating `state` in new higher order reducers

* Try moving synced pattern client ids into a separate reducer

* Revert "Try moving synced pattern client ids into a separate reducer"

This reverts commit e1d6ca4.

It doesn't really work, since reducer won't have access to `state.blocks.tree`.

* Try amalgamating the different derived block editing modes

* Fixes

* Fix synced patterns in write mode, unbound content blocks being editable

* Also update derived block editing mode on `REPLACE_INNER_BLOCKS

* Fix descending through controlled inner blocks

* Fix nested pattern handling - always process synced patterns in the reducer. Add special handling for only adding pattern block itself as content only when not in zoomed out or nav mode

* Zoomed out fixes - content should never be editable in zoomed out, even synced pattern overrides or when write mode is active

* Docs

* Add end to end test

* Remove navigation mode selector tests

* Fix partial mocking of blocks package

* Add test for isContentBlock

* Add unit tests

* Remove defaultBlockEditingMode concept

* Handle patterns that are outside sections in nav mode

* Remove comment

* Refactor to handle tree subsections

* Optimize each individual action

* Fixes and refinements

* Comments and renamings

* Remove test mocking - else test chokes trying to unlock privateApis

* Rework reducer unit tests and add more cases

* Add more tests

* Handle when the SET_HAS_CONTROLLED_INNER_BLOCKS block has been removed from the state

* Inline editing mode calculation for individual blocks

* Calculate both the regular and nav mode derived block editing modes at the same time

* Update getEnabledClientIdsTree dependencies

* Fix tests

* Update more tests

* Enable write mode experiment for e2e pattern overrides block editing mode tests
