This change implements support for filtering serial ports based on a USB
vendor and product ID. The naming of the filter properties comes from
the Serial API polyfill library where I felt it was important to be
specific that this filter will only apply to USB devices and so also
implies that the device being requested by the page will be a USB
device.

This is useful for applications which are targeting a particular model
of serial device that is known to be connected over USB and advertises
a recognizable vendor ID/product ID pair.
