Introduce support for Netty 5 Buffer

Browse Source 
This commit introduces support for Netty 5's Buffer, in the form of
Netty5DataBuffer. Because of the new API offered by Buffer, several
changes have been made to the DataBuffer API:

- CloseableDataBuffer is a simpler alternative to PooledDataBuffer, and
  implemented by Netty5DataBuffer. DataBufferUtils::release can now
  handle CloseableDataBuffer as well as PooledDataBuffer.
- PooledDataBuffer::touch has been moved into a separate interface:
  TouchableDataBuffer, which is implemented by Netty5DataBuffer.
- The capacity of DataBuffers can no longer be reduced, they can only
  grow larger. As a consequence, DataBuffer::capacity(int) has been
  deprecated, but ensureWritable (formally ensureCapacity) still exists.
- DataBuffer::slice and retainedSlice have been deprecated in favor of
  split, a new method that ensures that memory regions do not overlap.
- DataBuffer::asByteBuffer has been deprecated in favor of toByteBuffer,
  a new method that returns a copy, instead of shared data.
- DataBufferFactory::allocateBuffer has been deprecated in favor of
  allocateBuffer(int).

Closes gh-28874
