Separate Passive and Hostile Mob Grief in Game Rules

With allays fairly recently added, and copper golems coming in the next drop, I want to bring up the old community request that hostile and passive/neutral mob grief be separate game rules so that the new features are available to people who keep mob grief turned off because they play with kids or just don't like filling creeper holes all the time :) This would also mean villager breeding, dolphins playing, and sheep farms that rely on observers would be available for people who prefer to keep mob grief disabled. If neutral was included, piglin bartering would be simpler as well.
