This addresses https://github.com/eclipse/smarthome/issues/5099 by adding a command description with command options along with the state description.
Command options will give a hint to UIs about the specific commands a channel provides. Command options could be rendered as a drop down and also represent the current state or rendered as push buttons to simply send a command to the ThingHandler.
The infrstructure basically copies the StateDescription infrastructure with CommandDescriptionProviders and an `DynamicCommandDescriptionProvider` interface for bindings to hook in and provide dynamic command options.

The ready marker logic is created to hide the real usage. The ready
marker uses an "identifier" that is not specific or limited to bundles.
Currently the bundle symbolic name is used as bundle identifier.
That "convention" needs to be known at several different places.
There should be one method that created an identifier for a bundle and
"no one" needs to care about the implementation details.
Another point is that the bundle symbolic name that has been used is
optional. It may be null e.g. for bundles that has been installed by the
synthetic bundle installer mechanism etc.
The runtime assigns a bundle ID to an installed bundle that remains the
same for the bundle (see JavaDoc). The bundle ID is present all the
time.
The implementation of the "get identifier for bundle" has been choosen
to use the BSN -- if available -- (as before) but fallback to a custom
one using also the bundle ID (to be unique).
So we can provide always a non null identifier for a bundle.
It should be easily to change the identifier creation now if there is
every any need for.
