Root flake now only contains dependencies needed for building the NuttX
firmware. The Documentation flake contains the dependencies needed for
running `make html`.
Updated the documentation accordingly.

This commit introduces a Nix flake (flake.nix and flake.lock) to provide
a reproducible development shell for NuttX using Nix and flakes.
- Adds a devShell with all required build tools and dependencies for NuttX,
including CMake, Ninja, GNU Make, clang-tools, ARM toolchain, and other
utilities (automake, bison, flex, genromfs, gettext, gperf, kconfig-frontends,
libelf, expat, gmp, isl, libmpc, mpfr, ncurses, zlib, kconfiglib).
- Uses flake-utils to support multiple platforms.
- Sets up a shell hook to enable CMake compile commands and provide a welcome
message.
- Based on nixpkgs `nixos-unstable` for up-to-date packages.
Purpose:
- Simplifies onboarding and ensures a consistent build environment across
contributors.
- Reduces "works on my machine" issues by pinning dependencies.
Tested by running `nix develop` and building NuttX on x86_64-linux.
No impact on runtime or target builds; this only affects developer tooling.
For more details, see the new flake.nix file.
