Merge #968

968: CI playtests for Dx12, Vulkan r=kvark a=DevOrc

**Connections**
#950

**Description**
Implements CI testing for Vulkan and DX12. Also, cargo test stdout will no longer be captured so that people can verify that the playtests actually ran. 

Note: If no adapters are found, nothing will run and the tests will pass. This might become a problem if the installation no longer works and no one notices. 

**Testing**
Passed CI Tests
