[feature request] Support consumer client memory limit

### Motivation

The current CPP client supports memory limits by the client.

https://github.com/apache/pulsar-client-cpp/blob/872f8abaade7ecd346d3f59e2f6b3901c65ef7de/include/pulsar/ClientConfiguration.h#L36-L42

But this configuration does not limit the consumer's memory usage, We need to support consumer memory control first and use this parameter control uniformly.

### Alternatives

Refer to PIP: https://github.com/apache/pulsar/pull/15216
Refer to comment: https://github.com/apache/pulsar/pull/16903#pullrequestreview-1058047687

After this, we can control the memory limit through the client config.

### Anything else?

从 include/pulsar/ClientConfiguration.h 中的客户端内存限制配置开始，然后阅读所引用的 Pulsar PIP 以及关于拟议方案的 pull request 讨论。跟踪消费者内存的管理方式，并将完成定义为：客户端配置能够一致地控制消费者的内存使用量，且测试覆盖该限制。
