[roll] Roll fuchsia [netstack3] Rework IGMPv1 compatibility mode

Simplify some things around the IGMPv1 router present compatibility
mode.

- GMPv1 was pinging IGMP for every *group* instead of every query. This
  is entirely unnecessary and removing that simplified things in GMPv1.
- IGMP was keeping a timer for the only reason of flipping a boolean
  back to false on expiration. It's subtantially cheaper to just keep a
  local deadline and treat that as a value instead (esp because a single
  place in the code checks for it). Allows us to eliminate the entire
  alternate-timer workflow existing in IGMP.

Then, for symmetry with GMPv2 we forget the compat mode on disable.

And, finally, consider the current GMP mode to calculate the router
timeout since the RFCs define different values.
