Refactor layout constants in preparation for adding support for Material Hybrid.

Refactor layout constants in preparation for adding support for Material Hybrid.

* Uses layout constants for the tab height in all cases, not just material.
* Removes TAB_MAXIMUM_TITLE_WIDTH layout constant.  We really just want the total maximum tab width to be the same across all modes, so compute it that way directly in tab.cc.
* Adds a new GetLayoutSize() function, which currently is only used for the new tab button size.
* A few other tiny cleanups.

BUG=none
TEST=none
