Redis Client: add deployment SPI module

One build item, `RequestedRedisClientBuildItem`, is moved from the Redis Client
deployment module to the deployment SPI module. This is technically a breaking
change, because it is also moved to a different package, but this build item
doesn't seem to be used anywhere outside of Quarkus, so it should be safe.

Further, one new build item, `RedisClientBuildItem`, is added. It provides
runtime access to the Redis clients (in the Mutiny variant) without having
to perform a CDI lookup.
