Create v4 PathInterpolatorCompat

PathInterpolatorCompat uses PathInterpolator on API 21+, and provides an
alternative implementation to support API 4+. PathInterpolatorCompatIMPL
computes the interpolation along an arbitrary path using a linear
sample-based approximation. Note the interpolated values may differ
slightly from the framework PathInterpolator which uses an arc-based
approximation.
