Reapply CL for "Vertical Writing Mode" support.

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. Rotates the text in drawGlyphs for vertical writing mode.

Here are the changesets for Chrome's vertical writinig mode support:
1. http://trac.webkit.org/changeset/74232
2. http://trac.webkit.org/changeset/80610
3. http://trac.webkit.org/changeset/80654

This CL re-applies reverted CL136684(https://android-git.corp.google.com/g/#/c/136684/).
CL136684 was rollbacked because 2 constructors in FontPlatformDataAndroid.cpp
did not have the init for fontOrientation and textOrientation. That caused the
inconsistent comparison while FontCache.cpp tries to get the cached font and
falls into an infinite loop in HashTable.h:656
