Support "Vertical Writing Mode".

Bug 5094208 - Browser does not handle Japanese text in vertical writing mode.
This changeset syncs up with Chrome's implementation for vertical text rendering. It
1. Adds fontOrientation and textOrientation to FontPlatformData.
2. Re-layout the text in drawGlyphs for vertical writing mode.
