ultrareview nits: keep xfer_result table in sync, hoist blinky loop

- src/tusb.c: extend tu_str_xfer_result[] with "ABORTED" and "INVALID"
  to match the new enum size. Not reachable today (no HCD posts those
  values through hcd_event_xfer_complete), but keeps the enum/table
  invariant intact so future HCDs that surface ABORTED don't index OOB.

- examples/dual/dynamic_switch/src/main.c: apply the same while(1)
  hoist already done for cdc_task / print_devinfo_task to
  led_blinking_task. On OS_NONE the loop returned mid-iteration, which
  on first call could fire multiple back-to-back toggles while
  start_ms (initially 0) caught up to uptime.
