Floating point based Point/Size/Rect and Insets

This is copied from integer version, instead of using
template, to minimize conflict with m19 branch, as
using template requires updating forward declaration
of these classes in many places.
 I put this behind gyp flag for now so that we can move forward without breaking non DIP build until we can get aura
working with DIP.

BUG=114664
TEST=none
