RenderText work

Introduce a new header : render_text.hpp

This has new types, including a new virtual class RenderFont that clients need to subclass and provide.

This PR includes two experimental implementations:
- skia based (but trivial shaper : no shaping, no kerning, no intl support)
- harfbuzz based (good shaper, but no support for color glyphs)
Neither try to perform font substitution yet.

This PR has **no impact** on Runtimes yet -- it is just play code that Viewer can test.
