Remove Nausea Accessibility Option for Bedrock

Now that there's a common nausea effect in the game, that can't really be avoided, if a player wants to be able to play with the latest drop, an accessibility option of removing nausea is needed in Bedrock. There are no reasons to not do this - this is a very common accessibility option in games. Nausea effects are a well known problem for many players. And the option to toggle it off is in Java, so it's clearly not an effect you want players to have to suffer.
