Mitchell Hashimoto 984d123fe4 macos: support configuration via CLI arguments
This makes it so `zig build run` can take arguments such as
`--config-default-files=false` or any other configuration. Previously,
it only accepted commands such as `+version`.

Incidentally, this also makes it so that the app in general can now take
configuration arguments via the CLI if it is launched as a new instance
via `open`. For example:

    open -n Ghostty.app --args --config-default-files=false

This previously didn't work. This is kind of cool.

To make this work, the libghostty C API was modified so that
initialization requires the CLI args, and there is a new C API to try to
execute an action if it was set.
