Allow the user of SkCustomTypefaceBuilder to set the SkFontStyle of the resulting SkTypeface. This allows users to build font families. Fix the Font_flatten test to actually work (instead of relying on the magic behavior of nullptr for SkTypeface), add a test with the custom typeface, and reduce the number of times the inner loop runs from 302,400 times to 4,032 times so that the test finishes in a reasonable amount of time.
