Fix: Reactor emits critical error
Fix: Reactor emits critical error

Under normal usage, the reactor will emit this critical error:

```
[CRITICAL] kwargs must be passed inside the low data within the 'kwarg'
key. See usage of salt.utils.args.parse_input() and
salt.minion.load_args_and_kwargs() elsewhere in the codebase.
 ```

It seems like only `salt.utils.reactor.Reactor` uses `salt.state.Compiler`.
Due to this, it appears safe to customize `Compiler.compile_high_data`
for usage only by the reactor. Since reactor arguments are always named,
we ensure that each 'chunk' has an `arg` field that is an empty list
and a `kwarg` field that contains all the named arguments for use
with the given function call. This conforms to the format expected by
`salt.client.mixins.SyncClientMixin._low`.
