test: add GamePlayTests

[SilasPeters]

Description

The test to test all tests!
What it tests exactly, is expressed in the GamePlayTests.cs file.

In the process of making logic work, many gameobjects have been given a new layer.

Furthermore, this fixes a bug where an enemy can spawn in starting room.

The test is not optimised, some logic has been expressed but is not tested or visible with the current seed of the level, and it is not completely visible when the enemies get killed.
Furthermore, there is a bug in the game where you hit enemies that are not visible or out of range. Please ignore this, for this is out of scope of the game.
Also, yes the healing works but that is not visible in the current seed. That's simply because the agent is too smart. I will try to make him get damage somehow.

Testability

Run the tests. The scene is GamePlayTestScene.
