This implements a modified version of CDC ACM class driver
in a WebUSB compatible way. It adds the WebUSB descriptors,
custom and vendor requests handlers so that the host OS and
browsers can get the required BOS descriptor and supported
origins from the device. It also adds a custom interface
class so that the interface will not be claimed by the host
CDC ACM driver.
A simple echo app also included in this commit to demonstrate
how to create and use a WebUSB interface, as well as the
communication between browser and WebUSB enabled device.
