This fixes test failures when Ghostty's core is run without libc.
Ghostty in the real world (all built executables) require libc so this
bug has never been hit before, but I'm working on a libc-less core and
this caused real test failures (so its already tested, as well).
e0d6 and e0d7 were left out.
Also collapsed everything to a single range; unlikely that the unused
gaps (e0c9, e0cb, e0d3, e0d5) would be used for something else in any
font that ships Powerline glyphs.
...not whitespace. Powerline glyphs can be considered an extension of
the Block Elements unicode block, which is neither whitespace nor
symbols (icons).
This ensures that characters immediately followed by a powerline glyph
are constrained to a single cell (unlike the current behavior where a PL
glyph is considered whitespace), while symbols (icons) immediately
preceded by a powerline glyph are not (unlike if a PL glyph were
considered a symbol). This resolves

This makes more dependencies lazy. This has a practical effect of
reducing the number of dependencies that need to be downloaded when
running certain zig build steps.
This is all limited because we're blocked on an upstream Zig issue:
https://github.com/ziglang/zig/issues/21525 This prevents us from fully
avoiding downloading many dependencies, but at least they're relatively
small.
One major improvement here is the usage of `lazyImport` for
`zig-wayland` that prevents downloading `zig_wayland` unconditionally on
all platforms. On macOS, we don't download this at all anymore.
Another, weirder change is that all our transitive dependencies are now
marked lazy (e.g. glslang's upstream source) even if the glslang build
always requires it. This was necessary because without this, even if we
simply referenced glslang in the root build.zig, it would force the
source package to download unconditionally. This no longer happens.
cc @pluiedev Minor improvements here, doesn't change the long term plan,
but improves things in the interim.

This was not ported to gtk-ng before old runtime was removed, breaking
shell integration on Flatpak.
This implementation is copied verbatim from old runtime.
