feat: Introduce Flake for development and builds
This PR introduces a Nix flake, allowing for InfiniTime to be built as a Flake, including a FHS development environment. It's derived from #1850 and icewind1991/infinitime-builder@c57c57f. We also introduce `flake-compat`, allowing for non-Flake Nix mahcines to use the project as-is, both for building (`default.nix`), and development (`shell.nix`). Additionally, we introduce `.envrc`, meaning that with `direnv`, the Nix Flake is activated automatically. Fixes #1850. Signed-off-by: Dom Rodriguez <shymega@shymega.org.uk>
