The checkbox for selecting all rows only selects all the rows that have
not been filtered out. Changing the filtering does not change the
selection or the checkbox state so assuming that all rows are selected
simply because the checkbox has been checked cannot work.

Fixes #11479

Removal of data communicator needs to happen before call to super.remove() since super.remove() sets parent to null causing the NPE.

The old name GridDragger gave an impression that you're dragging the whole grid instead of rows.

This pathc also switches GridDragger to by default not allow drops on rows when the
grid has been sorted.

* Added Griddragger.

* Refactored the GridDragger to match FW style

Unit tests, Test UI and documentation to come next.

* Change DropMode to BETWEEN and add Test UIs

* Simplify GridDragger API

* Fixes and unit tests for GridDragger

Fixed issues regarding drop index calculation when sourche and target grid is the same.
When the ListDataProvider is not internally using List, always drops to the end.
Updates the old data provider instead of creating a new one to preserve filters&sorting.

* Add new drop mode ON_GRID for GridDropTarget

Also adds a way to not accept drops on rows when the user has sorted the grid.
This way the bad UX can be avoided for showing the drop indicator for the wrong place when the grid has been sorted.
This has not been made default behavior to GridDropTarget since it would change behavior compared to 8.1.
Instead if is triggerable via API in GridDropTarget.

* Refactor sorted grid drop logic to server side

* Block setDropMode calls

Blocking setDropMode set values if the grid has been sorted and drop on
sorted rows is not allowed. The value is used once the grid is not sorted
anymore or the drops are allowed on sorted rows.

Also use "event" as the name for events

* Use .toLowerCase and .toUpperCase(Locale.ROOT)

* Spaces

* add spaces after if(

* Simplify lambda expressions

And remove unneeded 'return' keyword.

* Format

Opening grid editor from server side.
