Merge branch 'mc-1.16.x' into mc-1.18.x

This is a noisier diff than I'd like as this is just a direct copy from
the multi-loader branch.

 - Rename "ingame" package to "gametest"

 - Don't chain GameTestSequence methods - it's actually much cleaner if
   we just use Kotlin's implicit this syntax.

 - Use our work in 71f81e1201 to write
   computer tests using Kotlin instead of Lua. This means all the logic
   is in one place, which is nice!

 - Add a couple more tests for some of the more error-prone bits of
   functionality.
