[Dash] Category expansion transition has variable speeds

[Oren Horev]

When a category expands in the Dash it executes the animation in a given duration. Because the extent of content that will be revealed (distance of travel) varies between one row to many rows. This caused the animation to appear fast when the travel distance is big and slow when it is small.

to reproduce :
in dash home expand frequent application category for slow speed
in apps scope - expand installed category for fast speed

desired behaviour :
animation should be maintained at a given speed taking into consideration the distance of travel expected

Actually this is still to fix - we need to make it ease linearly, otherwise there will always be speed-up / slow-down at the bounds.

Nicolas, please read above (comment #1).

This is a tad more complicated than it looks - we need to make it a two-step animation, taking into account the visible portion of the category, not just the target height.

Will revert the change that made it actually worse.

[Omer Akram (om26er)]

I think we should also revert the change that brought in the current
behavior. That does not looks good. or maybe increase the speed of that
animation will help.

I really don't see category expansion speed being an issue in the current builds. -> invalid.
