[WebSocket] Add support to consume Datapipe in network service

This commit adds support to network service to consume websocket frame
data from mojo datapipe produced from blink. To achieve this, this
commit adds a new message SendMessage() in mojo WebSocket interface.
It also adds SimpleWatcher to watch the consumer and be notified when
needed, and add callback function OnReadable() to support this.

This commit also adds ReadAndSendFrameFromDataPipe() to actually
consume data from the datapipe.

The producer side of the datapipe and the caller of SendMessage() are
not implemented yet for security review. WIP CLs are uploaded here:

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
