Add the minimum needed to drive a transfer ring from the test. Use it to
queue an isoch TD with SIA on usb-audio after stepping the clock past
2^32 microframes, and check that the TD waits for the next interval
boundary. Before the ROUND_UP() change it completed as soon as the
doorbell was rung.
The machine is started with pit=off. With the i8254 present the clock
step takes 26s in an ASan build instead of well under a second.

Notes:
Nick Piggin's v4 series has a fuller xhci ring harness for qtest:

The helpers here are self-contained so that the fixes do not depend on
it. I can rebase onto that harness if it is revived.
