The fake Arial already distributed with Python is based on Liberation fonts.
It is metrically compatible with the original Arial, but it doesn't support
all its glyphs (specifically, it misses Arabic).
The new one is based on Noto fonts. It support all the Arial glyphs
(I think), but it is not metrically compatible. It is enabled based
on SteamGameId when glyph coverage is considered more important than
metric compatibility.
So far it is enabled for FIFA 21 and FIFA 22.

The current script based on fontforge seems to have a few problems.
The generated fonts show glitches, for example in Cyberpunk 2077 for
Thai and in FIFA 22 for Arabic.
I don't precisely know what is the problem, and it might be that
the real bug is in the rendering code rather than in the merging
script. But since this seems to work better overall, I'm sticking
with it.

We can move everything but Liberation fonts build to the container.
Sadly those require newer version of fontforge than the one available in
the Steam RT.
There's some extra logic necessary to assure that font build triggers in
the container with the default/all targets.
This removes the requirement to have afdko and fonttools installed on
the host.
They are metrically compatible with MS Gothic fonts. Attack on Titan 2
- A.O.T.2 - 進撃の巨人２ and Touhou Fuujinroku ~ Mountain of Faith are
known to render better with Ume fonts.
