assets: vendor Inter, UDEV Gothic, Source Serif 4, and Noto CJK

The typefaces ADR 0024 settles on, fetched from canonical release URLs by
scripts/vendor-fonts.sh along with each upstream license. All SIL OFL 1.1.

Static instances only, one file per weight, never variable fonts: gpui loads
faces through fontdb and asks swash for metrics with an empty variation array,
so a variable font resolves at its default instance and every other weight
silently collapses onto it.

Filenames are lowercase-with-underscores because Android resource names must
match [a-z0-9_]. Rust is indifferent, so one naming scheme serves both
modalities and the bytes stay identical across them.

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
