## Description
In this PR,
- we are refactoring Anvil DnD to use dom elements to render highlights
instead of canvas.
Why?
- Doesn't have the ability to overflow a widget and still allow dnd
events(section widget use case)
- limitations with respect to being testable
- we are adding compensators to dnd layers, so that DnD is not just for
layout but for the entire widget.
Widget is the appsmith entity.
layout is something present in container like widgets like Section and
Zone which allow you to contain children widgets based on a the layout
structure.
What are compensators?
- additional padding for DnD layers in a widget
- additional position offsets for highlights in a widget so that they
don't stick to the layout.
Why compensators?
- Section widget can be activated to show highlights in areas
overlapping with main canvas
- DnD should be possible even at spacings created by parent widget like
in Zone widget
- we are also removing canvas activation logic and moving to using mouse
move event to activate a canvas for DnD.
