patch(Canvas): move event mouse:up:before earlier in the logic for more control

[ShaMan123]

Motivation

I want to disable mouseup default behavior from the mouse:up:before event
In mouse down it is possible with delete canvas._target, see

fabric.js/src/canvas/Canvas.ts

Lines 1061 to 1063 in 9c8e102

	this._cacheTransformEventData(e);
	this._handleEvent(e, 'down:before');
	let target: FabricObject | undefined = this._target;

In mouse up it isn't because of the order of execution.
So I changed the const target to be defined after the mouse:up:before event is called

Description

Please add this to beta15

LGTM. For a long-term solution, returning false from handleEvent sounds a better solution, or even checking event. defaultPrevented on the event.

definately, I agree

Changed isClick to populate only on up events including up:before
Removed used currentTarget currentSubTargets from the event data #9450
