- return nullptr for the various makeFromFoo() that we can't support,
and tweak a few unit tests to bail out early when they do
- create FontStyleSet and SkTypefaces once
- abort early from FontHostStream if we can't openStream()
- implement SkTestTypeface::onCreateFamilyNameIterator()
with SkOTUtils::LocalizedStrings_SingleName() so FontNames passes
- pin out-of-range glyph IDs to zero in SkTestTypeface
