zephyr: drivers: Extend BUILD_HOST_COMMAND macro
Now BUILD_HOST_COMMAND macro accepts params argument to setup parameters
of host command. New variants of BUILD_HOST_COMMAND are added:
- BUILD_HOST_COMMAND_RESPONSE
- BUILD_HOST_COMMAND_PARAMS
- BUILD_HOST_COMMAND_SIMPLE
They allow to declare host command with only response, params or
neither.
The response_size field is intentionally set to 0, because this is
default value. Command returning data should update this field.
BUG=none
BRANCH=none
TEST=make configure --test zephyr/test/drivers
