ICP-11103 - sending a supportedWindowShadeCommands event

[KKlimczukS]

There were some changes on the plugin side, so sending a supportedWindowShadeCommands event is needed now for shades to work.

Please, take a look.

Do we need to get existing devices to send this event? We could either add a call in parse() to check if the attribute is set and if not send the event, or run a script to update it.

Also, does the mobile client not work if that attribute is not set?

If the plugin now requires this I would suggest creating the event in installed and also creating it in parse if it hasn't already been created. That way we won't have to run a script to update existing devices.

@tpmanley @dkirker - according to Your suggestions - there are new changes in DTH.

[tpmanley]

This will need to be if (!device.currentValue("supportedWindowShadeCommands"))

[KKlimczukS]

instead of
if (!state.supportedWindowShadeCommands) ?

#11364
includes changes from this PR. I think we can close this one and focus on PR: 11364

[tpmanley]

I agree that we can close this PR. I addressed the same issue in #11355 and also generated the necessary event on all existing devices.
