Fixes #8918

Fixes #9663

Also update declarative writing to use true instead of "" for empty
attributes because of changed defaults in JSoup. For v7, the tests are
updated instead of touching the implementations.

Fixes `DateField blur event fires when focus gets to the "calendar button"` #1008

This patch fixes the BinderValidationStatusHandler example in the documentation.

* Fix missing v-disabled for RadioButtonGroup
* Fix missing v-disabled for CheckBoxGroup

Resolves #9258

* Changed retrieval of names of nested properties (#10159)

The getName() function in NestedBeanPropertyDefinition will return only the top level name, which causes problems when adding a nested property that has the same name as a non-nested (e.g "value" & "sub.value")

This change should fix this behaviour by changing the return value of "getName()" of NestedBeanPropertyDefinition and introducing a function "getTopLevelName()" that only returns the last part of the full name for where it's needed

This patch also adds ValueChangeEvent as a parameter to field value change method in Binder.

Deprecate com.vaadin.ui.components.grid.DescriptionGenerator
and subclass it from the new DescriptionGenerator.

* Accessibility for MenuBar (#3922)
* TabIndex handling fix and an indexing tweak
* Make disabled MenuItems selectable for accessibility (#3922)

- It should be possible to navigate to a disabled MenuItem, even if
triggering the related command is disabled

* Refactor primary style name and aria attribute handling to own method

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.

Fixes #10195

Fixes #9210

UIDL might contain sensitive information that we should prevent from
being stored anywhere.

Fixes #10292

From VDateField and VWindow

Based on vaadin/flow#2834

Make focus circulate in modal dialog to improve accessibility

* HasItems.setItems(T... items) should allow edits

Arrays.asList() creates a immutable Arrays.ArrayList, preventing users from doing dataProvider.getItems() and updating the returned collection. This makes it impossible to keep the same data provider, update it and keep the filters & sorting, and then just call dataProvider.refreshAll() to get changes visible. We should not require users to create a new data provider in this case.
This is the same for DataProvider.ofItems(T... items)

* fix missing whitespace from test error message

* Relax TreeGrid and Tree members access modifiers.

Fixes #10292

* Fixes after review

Because VConsole is deprecated and it recommends using Logger instead
