* Characters in symbol blocks that are also covered by Noto CJK fonts

they may also exist in the color emoji font, to make sure they get
a default text style.
* Characters that UTR #51 defines as default emoji are removed, to
make sure they don't block the fallback to the color emoji font.
* A few math symbols that are currently included in Roboto are added,
to prepare for potentially removing them from Roboto when they are
lower-quality in Roboto.
