This is a follow-up after OT refactor PR:
ckeditor/ckeditor5-engine#1459

Having just one MoveOperation with different type property value might simplify some places in the code. Right now, RemoveOperation and ReinsertOperation extends MoveOperation but aren't much different from it.

I hope this way we will be able to simplify getTransformation after this change.

See https://github.com/ckeditor/ckeditor5-engine/pull/1459/files#r204375812.

Other: Moved error logging from debug tools to OT code.
Other: Aligned `Schema#getValidRanges` results to changes in `AttributeOperation`.
Other: Unified `RemoveOperation` and `ReinsertOperation` to have just one `MoveOperation`.
Other: Simplified `LiveRange#event:change` second parameter which is now an object containing `Position` not an `Operation`.
Internal: Operational transformations refactor followups. 
Internal: Additional improvements for the new OT algorithms.
Internal: Added relations to better solve cases in undo.
Internal: Improved cloning mechanism inside `WrapOperation`.
Internal: Improved `model.Range#getTransformedByMergeOperation`.
Internal: Other improvements in OT algorithms.
Internal: Improvements in docs.

Closes #1468. Closes #1464. Closes #1467. Closes #1460. Closes #1461. Closes #1462. Closes #1463. Closes #1475. Closes #1479.

BREAKING CHANGE: `LiveRange#event:change` second parameter is now an object containing property `deletionPosition`. It can be `model.Position` instance, if the range was moved to the graveyard root. The position is equal to the position from which nodes were removed. Otherwise, it is set to `null`.

BREAKING CHANGE: `Schema#getValidRanges` will return only flat ranges now. If an attribute is allowed on some nodes and in those nodes children, multiple "nested" ranges will be returned.

BREAKING CHANGE: `Schema#getValidRanges` is a generator now.
