Cleans up a whole bunch of things I wanted to get out of the door right away: * depot internal references to //third_party/nixery have been replaced with //tools/nixery * cleaned up files from Github * fixed SPDX & Copyright headers * code formatting and inclusion in //tools/depotfmt checks Change-Id: Iea79f0fdf3aa04f71741d4f4032f88605ae415bb Reviewed-on: https://cl.tvl.fyi/c/depot/+/5486 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su> Autosubmit: tazjin <tazjin@tvl.su>
