r/aws_elasticache_cluster: add configurable timeouts (#41940)

The registry documentation for the `aws_elasticache_cluster` resource already includes a `Timeouts` section, however, these were hardcoded into the Create, Update, and Delete methods and not configurable. This change adds configurable timeouts using the pre-existing hardcoded values, allowing practitioners to adjust the timeout values as needed (and as the registry documentation already implies).
