[exceptions] Protocol for "ffx debug limbo"

Add extra APIs in ProcessLimbo that will be used by `ffx debug limbo`.
Existing Watch* APIs are not working because

- They enforce a hanging get pattern which is undesired sometimes.
- The return value of WatchProcessesWaitingOnException contains
  zx.handle:PROCESS which cannot be transported in Overnet.
