fix(list): allow for list and list items to be disabled

[crisbeto]

Adds the ability to disable all variants of the list. Currently it's only the selection list that can be disabled.

Fixes #17574.

How's the contrast ratio on disabled items?

[jelbourn]

This would also disable tooltips, I think we'd want to avoid

[crisbeto]

How would we prevent clicking on it though? We've done something similar to support disabled tabs in the tab nav bar.

[jelbourn]

Yeah, the tabs thing is why I thought about this (someone mentioned it in a bug). I don't know of another way to do this other than preventDefault / stopPropagation

[crisbeto]

We can't rely on preventDefault/stopPropagation, because we don't have a way of ensuring that our event listeners are invoked before the user's.

[crisbeto]

Sorry for the delayed response @jelbourn, I must've missed the notification. The feedback has been addressed, can you take another look. As for the contrast ratio on disabled items, I haven't checked it but it's the same as what we have in master for selection lists.

[Ammonix]

when will this get merged?

[jelbourn]

LGTM

I guess native controls don't show their title tooltip when disabled, so it makes sense for our stuff to do the same.
