This adds a new way of dumping descriptors, which splits the knowledge
of how to interpret descriptor data from the actual dumping. This has
two advantages:
1. It is easy to add support for new descriptors, since they are now
simple definitions that resemble the tables in the USB specifications.
2. The code for dumping descriptors is common, so the output is easy to
keep consistent. It is also consistent and thorough in its handling
of insufficient descriptor data buffer, and junk data at the end of
a descriptor.
UAC1 and UAC2 are converted to use the new mechanism, initial support
for UAC3 is added. Finally, support for the USB3 BOS Configuration
Summary Descriptor is added.
