Add default metadata for lights entities

[helto4real]

Breaking change

Proposed change

This PR includes default metadata for light domain so we can get default values for attributes like Brightness even if the lights are off when generating the first time. This PR also deprecates the usage of UseAttributeBaseClasses setting since this chage makes it obsolete and much easier to include additional default metadata for other domains in the future.
