Closes #13290
This reduces the number of times we do a
ByteBuffer.slice()when sending a frame in WebSocket, now the buffer of the Frame is consumed after the call toCoreSession.sendFrame.Currently this PR has the potential to impact users of Jetty / Jakarta WebSocket, as now the ByteBuffers sent with the sendBinary methods will consume the buffer.
But the Jakarta API now does specify that the container should consume the ByteBuffer (see discussion on jakartaee/websocket#209).
