Implement `gn edit` command, and implement a simple subcommand "set"

`gn edit` is a command heavily inspired by buildozer
(https://github.com/bazelbuild/buildtools/blob/main/buildozer/README.md).
It allows programattic editing of BUILD.gn files.

It is a soft requirement for the rollout of strict deps, and has three
primary use cases:
* Make AI able to edit build files more effectively
* Make large-scale rollouts easier to perform.
* Put the infrastructure in place for `gn check --fix` / `gn suggest --apply`
