Support USB 3 SuperSpeed

Add support for emulation of USB 3 SuperSpeed devices. A non-exhaustive list of potentially required changes:

  • Allow verifying that the UDC is SuperSpeed-capable (requires #41);
  • Accept endpoint companion descriptor when enabling endpoints;
  • Allow providing stream_id for bulk transfers;
  • Set ep->maxburst (for bulk and interrupt endpoints) and ep->mult (for isochronous endpoints; requires #60).

This issue is also mentioned in the kernel documentation.
