Add shell.nix

Browse Source 
This makes it possible to execute `nix-shell` to create the correct environment to build kitty. Use `nix-shell --pure` to eliminate most of the influence of the outside system, e.g. globally installed packages.
This works on NixOS and any Linux or macOS system with the Nix package manager installed.
The build inputs are split into `buildInputs`, `nativeBuildInputs`, `propagatedBuildInputs` and `checkInputs` so it closely resembles 2bb3a9da24/pkgs/applications/terminal-emulators/kitty/default.nix. This makes it easy to port changes between the two files.

Build and run from source with Nix
-------------------------------------------
On NixOS or any other Linux or macOS system with the Nix package manager installed,
execute ``nix-shell`` to create the correct environment to build kitty or use
``nix-shell --pure`` instead to eliminate most of the influence of the outside system,
e.g. globally installed packages. ``nix-shell`` will automatically fetch all required
dependencies and make them available in the newly spawned shell.
Then proceed with ``make`` or ``make app`` according to the platform specific instructions above.
Note for Linux/macOS packagers
