Add a matrix of stdenvs to the flake
For a (currently hardcoded and limited) list of stdenvs,
make `.#$nix-${stdenvName}` correspond to a Nix built with the
corresponding stdenv.
For example, `.#nix-${clang11Stdenv}` is Nix built with clang11.
Likewise, `devShells.x86_64-linux.clang11StdenvPackages` is a development
shell for Nix with clang11, that can be used with
```shell
nix develop .#clang11StdenvPackages
```
Fix #4129
