Adding a toggle for suffocation while generating spheres, pyramids, etc.

### The Problem

Hello,

I after doing some terraforming I wanted to patch and fill the holes that were created in the terrain.
Some of these terrains are very intricate, so using the fill command or any kind of selecting to patch holes is not very practical.

Example (holes in red):

So, what I was doing to fill the holes: going into Spectator mode to reach these holes and run commands such as //sphere to fill them.

Issue: After running the command, while succeeding in patching the hole, it teleports me at the surface. It is a bit infuriating when I must run the command multiple times, which means I must travel back to the hole every time.

I have discussed the matter with "Wiz" on Discord, who told me it was a leftover from the old days where creative mode did not exist, so generating spheres and other forms may suffocate you, so as a patch, it teleports the player to the surface to avoid killing them.

They then suggested me that this feature could be a toggle when switching to spectator mode, or even creative.

### A Solution

Having a toggle in the config, or, disabling this "teleport-to-the-surface" feature when using Creative or Spectator mode.
