Reorganize system font APIs
This CL reorganizes the system font related APIs with following things:
- Move match function from system_fonts.h to new header file.
The matching logic is not only for system fonts. The custom font or
custom fallback Typeface can be a target of this matcher.
- Introduce new struct AFontMatcher for keeping matching rules.
This is for future extensibility. We may add another parameter for
querying fonts in future.
- Renamce ASystemFont to AFont and moved to new header file.
This is mainly because for future improvements.
Currently we don't have any plan for doing this in Q timeline, but the
matcher object can be used for Java Typeface object via JNI. For
example, build Typeface in Java and pass down to JNI and query the font
for the passed Typeface.
