Tom Fitzhenry 889571cf97 nixos/tests/grub: split into a directory and expand coverage ...

Move nixos/tests/grub.nix to nixos/tests/grub/basic.nix unchanged, and add
new GRUB boot tests under nixos/tests/grub/:

- hashed-password: GRUB user authentication with a
  users.<name>.hashedPasswordFile (a grub-mkpasswd-pbkdf2 hash). The hash is
  generated in a derivation and passed by store path (via toString) rather
  than read at evaluation time, to avoid import-from-derivation. Kept separate
  from basic so each login is exercised on its own VM boot rather than
  multiplexed onto one menu.
- efi: boot through GRUB's EFI support.
- graphical: verify GRUB renders its menu in graphical (gfxterm) mode. A
  marker string is baked into the splash image (which GRUB only draws in
  gfxterm) and read back via OCR, so a silent fallback to text mode would
  fail the test rather than pass it.
- mirrored-boots: verify GRUB is installed and configured on every path
  in boot.loader.grub.mirroredBoots.
