[MCPE-39590] World host can evaluate selectors even when cheats are disabled

The world host can use target selectors in commands like /tell, even when cheats are disabled. This allows them to get information they should not have access to.

Parameter(s)	Example	Leaked Information
`x y z r rm dx dy dz`	`/tell @a[x=0,z=0,r=10] hi`	Locations of players and coordinates in the world.
`scores`	/tell @a[scores=\{something=15..}] hi	Scoreboard objective names and player scores for internal objectives.
`l` `lm`	`/tell @a[lm=30] hi`	Amount of levels a player has.
`m`	`/tell @a[m=0] hi`	Internal gamemode IDs and gamemodes of players.
`ry rym rx rxm`	`/tell @a[rxm=0,rx=0] hi`	Direction a player is facing.

Other players without cheats are told "insufficent permissions for selector expansion."
