Let variable axes override existing or determine style information
with priority over FreeType face flags or information
from the OS/2 table.
Add test case for matching a variable fonts through SkFontMgr_FCI to
ensure the weight determination from variable axes is exercise.
The test does not exercise width or slant.
Add a small (~8.5k) subsetted Noto Sans CJK collection as a test font
(made using [1]), and ensure that matching, reported font style and axis
configuration are correct after matching.
