Log Message: ----------- 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.

Log Message: ----------- 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.
