FreeCad has addon system with various addons around the net.
It has an addon-manager which allows to browse through
registered addons and install them in runtime. But this is not nix-way,
because you have to install addons again after system configuration
moving.
Additionally freecad allows you to manually install addons and put them to
common folder or specify with command arguments.
This patch introduces extra `customize` method to FreeCad derivation
attrset (inspired from vim) which allows you to inject addons from nix
configuration.
```nix
{ freecad
, fetchFromGitHub
}:
let
cad-exchanger = fetchFromGitHub {
owner = "yorikvanhavre";
repo = "CADExchanger";
rev = "5c2cd792ddc4581b917ebe7add5ef960bf6c3e2a";
hash = "sha256-AST5bwhgMbvW3m8V1cv5PqKjJi2eSE1lbXpVLvRVzM8=";
};
freecad-customized = freecad.customize {
modules = [ cad-exchanger ];
};
in
freecad-customized
```

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
