HadoopStreams to support ByteBufferPositionedReadable input streams

### Describe the enhancement requested

If a stream declares in its StreamCapabilities that it supports
ByteBufferPositionedReadable, then use it for `readFully(ByteBuffer)`
All streams in Hadoop 3.0.0 + do declare this.

+ use StreamCapabilities to look for `ByteBufferReadable`.

For detecting ByteBufferReadable, use this probe falling back to the recursive scan.
All streams in the hadoop codebase will report this via StreamCapabilities, but there
may be some third-party streams which do not.

### Component(s)

_No response_

从 HadoopStreams 的实现开始，跟踪 readFully(ByteBuffer)，然后检查如何使用 StreamCapabilities 和现有的递归扫描来检测可读流。完成标准是：声明 ByteBufferPositionedReadable 的流使用该能力执行 readFully(ByteBuffer)，而第三方流仍回退到递归扫描。
