Meteor turfs typecache (#78152)

## About The Pull Request

When looking why meteors randomly explode sometimes, the check has it
taking damage and exploding from turfs that it should just be flying
over. This creates a typecache of turfs the meteor shouldn't deplete
health from flying over. Most commonly openspace and asteroid baseturf.

## Why It's Good For The Game

Meteor is more likely to explode when it actually hits something vs
flying into an openspace tile.

## Changelog

🆑 LT3
fix: Meteors no longer take damage from crossing certain unoccupied
turfs
