fonts: Provide an alternative fake Arial font.

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.
