WebSocket: Rename DocumentWebSocketChannel to WebSocketChannelImpl

DocumentWebSocketChannel is used for WebSocket on Document, but it's also used
on WorkerGlobalScope when the off-main-thread WebSocket is enabled. This CL
renames DocumentWebSocketChannel to WebSocketChannelImpl for reducing confusion.

Before this CL, the class hierarchy is as follows:

- WebSocketChannel
  - DocumentWebSocketChannel
  - WorkerWebSocketChannel
  - MockWebSocketChannel

After this CL, the class hierarchy is as follows:

- WebSocketChannel
  - WebSocketChannelImpl
  - WorkerWebSocketChannel (to be removed)
  - MockWebSocketChannel

After the off-main-thread WebSocketChannel is enabled by default,
WorkerWebSocketChannel is removed.
