6.0: Rename `EntityTrait::_accessible` property to something more appropriate

[LordSimal]

Description

I never really liked the name of the _accessible property inside our Cake\Datasource\EntityTrait since just by its name it indicates some sort of permission system to prevent (general) access to specified properties inside PHP... which it doesn't do.

The concept of mass assignment is properly described in the Docs and the baked entity classes also have a somewhat suitable explenation of what is happening but still the property name itself is a bit missleading imho.

Here are some of my (bad) suggestions that came to my mind:

• massAssignable (to be right on the nose but still what does assignable mean)
• massEditable (although this also doesn't represent it correctly because $entity->set('myfield', 'value'); would also be blocked if myfield is set to false)

Would love to hear your thoughts on that one 😁

massAssignable :+1:

Given that most folks interact with mass-assignment via the ORM methods, what about patchable?
