  1. rpmsg: Add API for retrieving message buffer sizes 

    Add an RPMsg API to get the buffer sizes supported by the backing
transport layer. Add hooks so that transport layers can register
functions to provide this data.

  3. apps: Convert examples to rpmsg_get_{tx,rx}_buffer_size() 

    The contents of app() in these examples is given a rpmsg_device. We should
not have to know about the backing transport layer. We assume it is virtio
and call into the virtio layer to get the buffer size. This information is
now available from the rpmsg layer. Use those functions to make the app()
agnostic to the backing layer.
