Changes in v2:
- Pick up Acks from John.
- Extend the description of "Explicitly list the tested clocks" patches.
- Drop some more custom ?SEC_PER_?SEC definitions.
- Drop SKIPPED_CLOCK_COUNT from nsleep-lat.c.
- Explicitly handle timer_delete() failure in nanosleep.c.
- Link to v1: https://patch.msgid.link/20260730-auxclock-nanosleep-prep-v1-0-cd8b61229a7c@xxxxxxxxxxxxx
