When font fallback involves monospace fonts, and if word has known
scripts, limit the fonts tried for fallback to ones that support at
least one requested script.
Codepoint support info is still collected for these fonts to guide
the fallback order selection process.
A map of per-script monospace font-ids is pre-populated in font system
to acquire lists of wanted font ids efficiently.

This should/could improve fallback order.
This could also probably be utilized for non-Monospace fallback too.
But I didn't want to touch that code to avoid accidentally breaking
anything.

A combination of some ideas:
* Try all Monospace fonts before giving up.
* Relax exact weight restriction on font matching when trying Monospace
fall-back. Try smaller weights if needed.
* Make the fall-back try order weight-offset aware, AND script-aware.
* And finally, add the option to adjust the font size of glyphs using
fall-back Monospace fonts, so the width of them matches the default
font width.
For my use-case, the current fall-back attempt always fails with
Arabic script. And none of the Arabic-supporting Monospace fonts in
my system also support medium weight. So, if my default font is set
to medium weight, script-aware fall-back alone will still not work.

This reduces compilation time by removing a dependency on syn and other
dependencies of ouroboros_macros. In addition it saves a lot of unused
codegened methods.
On my laptop (2 core + HT) this reduces compilation time by ~20%. On a
many core system this doesn't help much though as the critical path path
consists of both ttf-parser -> rustybuzz and swash. Further gains will
likely need to be made by reducing compilation time for these crates.

The code is based on an expansion of the ouroboros macro, cleaned up to
remove all unused methods and inline most functions that are only called
once.
