Introduce lambda-based modifiers

This CL introduces some lambda-based modifiers to change the alpha,
paddings or size of a Composable without triggering recomposition when
those values change. This is especially useful when animating these
values, which happens a lot in the SystemUI shade given that a lot of
components size/alpha is driven by touch gestures.
