Add TransitionInterpolation class for CSS Transition refactor

Add TransitionInterpolation class for CSS Transition refactor

This patch is part of refactoring CSS Transitions to use
CSSInterpolationTypes instead of AnimatableValues:
https://codereview.chromium.org/2680923005

The TransitionInterpolation class is a sibling of
InvalidatableInterpolation and does the same thing except it does
not need to deal with additive animations, keyframes being
invalidated by the environment and needing reconversion of the
InterpolationValues.
