RFR: 8308144: HttpClient - uncontrolled memory consumption in SSLFlowDelegate.Reader

[zhurs]

When using HttpClient to make requests to HTTPS resources, there is an issue where the entire file is being downloaded into memory without the ability to limit the buffer size.
If the SSLEngine cannot decode the entire buffer due to the algorithm's blocking nature, it returns a decoded chunk of data and BUFFER_UNDERFLOW status, which leads to SSLFlowDelegate.Reader requesting more data despite the output queue being full.
