platform/chrome: cros_ec_proto: Introduce cros_ec_get_cmd_versions()
Retrieving the supported versions of a command is a fairly common
operation. Provide a helper for it.
If the command is not supported at all the EC returns
-EINVAL/EC_RES_INVALID_PARAMS.
This error is translated into an empty version mask as that is easier to
handle for callers and they don't need to know about the error details.
