Binding the TypefaceFontProvider in skparagraph module

[MeetWq]

It's useful for building FontMgr from specified typefaces, e.g. reading fonts from a path set by the program and building the FontMgr for Paragraph.

I remember seeing an upstream example of a fontmgr loading an entire directory of fonts, can't find it quickly at the moment. Maybe that's an alternative.

@MeetWq I found what I mentioned : https://github.com/google/skia/blob/main/include/ports/SkFontMgr_directory.h - this might be much better as it is core API rather than module's.

@MeetWq gives the CI build in #293 if you want to try it out. See the tests for usage. As I wrote earlier it is somewhat similar to #292, which you might have a try too.
