Material Hybrid mode for tabstrip.

Material Hybrid mode for tabstrip.

Mostly this involves parameterizing the tab and new tab button drawing so they
can handle different desired sizes.  There should be no change in material
(non-hybrid) mode.

This also positions the new tab button vertically based on the distance below
the button instead of the distance above, since we want the gap between the
button and the toolbar to remain constant even as the tab and button heights
change, rather than having the button starting a fixed distance below the top of
the tabs.

BUG=519020
TEST=Run with --top-chrome-md=material-hybrid and check that the tabs and new tab button are larger than in material mode but still shaped correctly
