This PR passes in some args to the before_run_command hook so callbacks have some more context to base their logic off of.

The reason for proposing this change is because of a particular use case I have where I'm implementing some logging to track CLI commands that are being run in our codebase. I currently have an implementation that looks something like:

WP_CLI::add_hook( 'before_run_command', function() {
	$runner  = WP_CLI::get_runner();
	$command = $runner->find_command_to_run( $runner->arguments )[0];
	log( $command->get_name() );
} );

This works for commands invoked from the command line but doesn't work for commands invoked via WP_CLI::run_command with launch => false set. This is because run_command will call the Runner->run_command() method directly so the Runner instance doesn't get bootstrapped again with the proper context.

To get around this, I'm proposing we pass the params from the run_command method into the before_run_command hook.
