To avoid lock contention in Skia, use HarfBuzz implementation
for retrieving boundary box and advance information from font.

Since switching to 64-bit devices, size_t is now a 64-bit integer.
FontCollection::Range uses two size_t integers but they just point to an index
in mFamilies. To reduce the memory usage, this CL changes the size_t integers to
uint8_t.
The maximum size of each integer in Range is the size of FontCollection::mFamilies.
The largest this can go is the system font list plus a user defined family, which
has 91 families. So an 8-bit integer should be enough.
With this change, about 84 KiB of memory will be saved per font collection. Since
eight font collections are created during bootstrap, about 670 KiB of memory will
be saved with this CL.

Test: Ran FontCollection.collectionAllocationSizeTest on a 64-bit device.
On my Nexus 5X, it changed from 327358 to 241342.

Add an "mJustified" for justification, and tune the line breaking to
produce good results. Major differences for fully justified text include:
- Space can be shrunk in justified text.
- Hyphenation should be more aggressive in justified text.
Also adds a penalty for the last line being very short. This is tuned
to be more aggressive for ragged right than for justified text.
This is based on a patch by Raph Levien (raph@google.com).

* This allows the tests to add their own FLX files but still use consistent fonts.
* The test fonts are only embedded on the desktop test shells. The option is not available on mobile platforms.
* Right now, all fonts will resolve to the test font. If we want tests to be able to use the fonts they embed in FLX files but use the test font for platform fallbacks, we will need to add font selector fallbacks. I can do this in an another patch. So far, there are no users of this functionality.
