Thanks to Qyriad, it was found out that Nixpkgs was unable to cross
compile when CMake was needed at cross compilation time with Meson
because Meson refuse to use the ambiant CMake.
A simple fix is to always provide the ambiant CMake and trust the
packager to pass the right CMake, otherwise the rest of the build would
probably fail in mysterious ways.
An example of package that required this fix is the Lix, a Nix
implementation, that uses `toml11` discovered via CMake during the Meson
configure phase.

This fixes at least one bug with default-features, and also
just aligns us more with what Cargo actually does.
Also some Python style fixes and a bit less mutating state.
This fixes:
Could not load ICU data. UErrorCode: 2
We're using a hook instead of a wrapper because various things like to
reference the unwrapped dotnet executable.
This was achieved using the following command:
sd 'wrapGAppsHook\b' wrapGAppsHook3 (rg -l 'wrapGAppsHook\b')
And then manually reverted the following changes:
- alias in top-level.nix
- function name in wrap-gapps-hook.sh
- comment in postFixup of at-spi2-core
- comment in gtk4
- comment in preFixup of 1password-gui/linux.nix
- comment in postFixup of qgis/unwrapped-ltr.nix and qgis/unwrapped.nix
- comment in postFixup of telegram-desktop
- comment in postFixup of fwupd
- buildCommand of mongodb-compass
- postFixup of xflux-gui
- comment in a patch in kdePackages.kde-gtk-config and plasma5Packages.kde-gtk-config
- description of programs.sway.wrapperFeatures.gtk NixOS option (manual rebuild)

This is an increase of 4.4%, but OTOH zstd has a significantly higher
decompression speed[1].

Closes#302291Closes#301536
The following things have changed:
* For 5.7+: ZSWAP compressor uses zstd now.
* For 5.11+: ZRAM compressor uses zstd now.
* For 5.13+: kernel modules are compressed with zstd instead of xz.
* For 5.19+: support zstd-compressed firmware.
The modules-closure functionality needed explicit support for copying
over `.zst` files. Also, the VM image builder used busybox's `insmod`
before which doesn't support zstd. Switched to `kmod` and added xz/zstd
as dependencies for it, similar to how it's done for the actual stage1
in d33e52b253. The use of `kmod` here
doesn't seem to be such a big deal since it's only a build-time
dependency.
Since the tool is exposed more prominently now, we should clear up what
it is and note that it is to be considered unstable, i.e. we may change
it if the necessity arises. (In practice it is probably going to be
fairly stable though, as compiler interfaces tend to be quite stable.)
Should we add a version?
The cc and bintools wrapper contained ad hoc bootstrapping logic for
expand-response-params (which was callPackage-ed in a let binding). This
lead to the strange situation that the bootstrapping logic related to
expand-response-params is split between the wrapper derivations (where
it is duplicated) and the actual stdenv bootstrapping.
To clean this up, the wrappers simply should take expand-response-params
as an ordinary input: They need an adjacent expand-response-params (i.e.
one that runs on their host platform), but don't care about the how.
Providing this is only problematic during stdenv bootstrapping where we
have to pull it from the previous stage at times.
We don't need to artificially make sure that we can execute the wrapper
scripts on the build platform by using stdenv's shell (which comes from
buildPackages) since our cross infrastructure will get us the wrapper
from buildPackages. The upside of this change is that cross-compiled
wrappers (e.g. pkgsCross.aarch64-multiplatform.gcc) will actually work
when executed!
For bootstrapping this is also not a problem, since we have a long
build->build platform chain so runtimeShell is just as good as
stdenvNoCC.shell. We do fall back to old ways, though, by explicitly
using the bootstrap-tools shell in stage2, so the adjacent bash is only
used from stage4 onwards. This is unnecessary in principle (I'll try
removing this hack in the future), but ensures this change causes zero
rebuilds.
