refactor(Group): parent + fix(ActiveSelection): transferring object

[ShaMan123]

Motivation

I was looking into the patch I made into #9336 and understood that getParent was a design mistake.
It is confusing and silly. I wrote it in a haste, not wanting to create too many changes.
It is a design mistake IMO mainly because there is a confusion about active selection - should it be considered a parent or not.
Apps might need to access both the the current group of an object and both the owning group.
Since group and canvas are used it seems bad that to get the owning parent you do getParent(true).
I regret it.
This PR makes it simpler both for fabric and for devs and removes ambiguity of the group property.
Please accept it before v6 so it only breaks beta.

Description

This PR introduces the parent property on Object and removes getParent.
The parent property is the owning group of an object, meaning not the active selection.

While testing the PR I realized I didn't take into consideration another part of transferring an object between active selections that I missed in #9336
The object should be removed from the active selection and not be reomved from its owning group.

I need to assess if this should be merged into #8951 or done on top of it but they are duplicates to some extent
