Support include and exclude for property groups

Renders device properties for the thermostat group on /thermostats.

@DebbieAtSeam Didn't realize this until now, but we will need to be able to group the errors and warnings.

@razor-x How do we get this to say "The thermostat Object" instead of the "The device Object"?

[razor-x]

There is no thermostat object. This is a device resource. Should we say something else here that is more accurate, e.g., that these are the relevant properties of device for using the /thermostats API? Let's decide on the language first and we can adjust the template. We will likely need to incorporate this into the path metadata.

@DebbieAtSeam This one should be good to go now. We can keep adjusting the groups as needed but the codegen logic here should be correct now. The larger diff is because a sorted the groups and variants.

Side note, for sorting stuff, if needed we could introduce some kind of priority annotation, but I think this is a later problem to solve.
