In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

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)
scons build system does not work by default in nixpkgs envoironment as
it filters system environment and throws away NIX_* flags:
https://scons.org/doc/2.1.0/HTML/scons-user/x1750.html
Fix build system to always propagate os.environment. Drop the
workarounds that pass subset of the variables through.
rmlint has a `--gui` option which is writing a python "bootstrap" script
in `/tmp`.
It currently can't find its own python modules, as we don't prefix
`PYTHONPATH` to point to it. Also, there's some other runtime
dependencies, mostly due to using gtk from python(3), which also needs
to be preprended to `PYTHONPATH`.
The `rmlint` GUI components also execute `rmlint` again with `--version`
to determine some features, for which we need to prefix `PATH` with
`$out/bin`.
