SLING-12279 - Use ResourceResolver#getPropertyMap() for resource/resolver adaptables

[paul-bjorkstrand]

• Update Sling API dependency to 2.24.0 (to be able to use ResourceResolver#getPropertyMap()).
• Create a common cache holder object for all types of caches.
• When the adaptable is a request, continue to keep only a single cache mapping adapter types to adaptation results.
• When the adaptable is a resource or resource resolver, store the cache holder in the appropriate resource resolver's property map (this map has the same lifecycle as the resource resolver).
• When the adaptable is anything else, use the "global cache".
• When the cache holder is not global, remove the use of synchronized maps (moderate performance improvement since resources/resolvers should only be used single threaded).
• Ensure the Request cache holder's close() is called when the request is disposed.
• Update tests where needed.
• Add tests for new code.
