[Cache] Allow usage of Caffeine and Redis at the same time

[brunobastosg]

Description

Currently, the Quarkus cache extension only allows one cache provider (Caffeine or Redis) per application. It would be very useful to support configuring and using both providers at the same time, so different caches can use either in-memory (Caffeine) or distributed (Redis) backends as needed.

This would allow more flexible caching strategies within a single application.
