Port the runtime and translator fixes from upstream's KartPad batch

Browse Source 
From patchzyy/Wiicompiled 6f14bde (#244), runtime and translator parts only:
- Keep KD and NCD devices available while networking is off; only IP and
  SSL need the network.
- Run RFLiIsWorking's alarm pump in a private interrupt context so callback
  register writes don't clobber the caller, and release the alarm recursion
  guard before rescheduling.
- Share one LR continuation dispatch per translated function when it has
  several continuation calls.

The renderer half of that commit is left out: it conflicts with the stereo
renderer, and upstream reverted part of it (e409d9f) for stutters.

(cherry picked from part of commit 6f14bde26a4ed6390d4f18e1b3a9c1be6819d589)
