Allow multiple styles for fallback fonts

Fallback fonts are now recorded with their styles in the list of
available fonts (which is now a doubly-linked list). NextLogicalFont()
has a new parameter, providing the originally requested fontID, from
which we can determine the requested style, which we then pass to
find_best_face() to pick from the available styles.

SkFontHost::NextLogicalFont() no longer assumes that origFontID is
valid (see http://b/issue?id=4980240).
