Split TabStrip ideal layout code into a new file.

This patch creates TabStripLayoutHelper, a new class that is reponsible
for ideal bounds generation. Since both Tab Groups and Tab Scrolling are
about to add a lot to this step, this will prevent that complexity from
being visible to TabStrip, which is already complex enough.
