[LVGL] Add "screen stack control" property to Change Screen action

[zalexzperez]

If we need to change screen without adding the active one to the stack, we need the missing Set Active Screen action.
In order not to create a new action just for this, it makes sense to have a "Put active screen on the stack" option - enabled by default - on the Change Current screen action.

I added a new property called "Use stack":

The property seems to come disabled by default. And also, it's marked in red as if it requires user intereaction

The property seems to come disabled by default.

Fixed.
