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
c57c57f3c6.

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.
