Add a way to get specific constraint to animate components.

UI often runs animations with updating the constant value of the constraint.
Mondrian API is a faster way to get the whole layout, but still not have a way to get one of the constraints which would be used in animation.

hey! thank you for this great library! i would like to know if there is a way to update a constant value for now. is it impossible for now?

@ozgur-nent
thanks.
For now, we can find a constraint we needed from LayoutBuilderContext. but it's hard.

would you give me your detailed use case?

@muukii thank you for your answer. i wanna change top space of a view (to hide a view when user scroll the collectionview to bottom)

[muukii]

@ozgur-nent I see, could you paste your example layout code? I'd like to know what layout blocks you're using.
