cros: add `help` subcommand

The lack of a `help` subcommand for `cros` catches me out regularly, so
this CL adds one that's basically an alias for `cros [subcmd] --help`.
Unfortunately it doesn't look possible to implement it using the same
pattern as the others, as it doesn't have access to the argparse
subparsers object.

BUG=none
TEST=try it with a few subcommands (e.g. `cros help flash`)
