[graphics_pipeline] Wireframe mode crashes for Vulkan build

[angela28chen]

Specifically for Vulkan and not DX12 build. I tested this with a fresh clone as well to make sure it wasn't issue #349

To repro: vk_graphics_pipeline.exe --debug-view "Wireframe Mode" Or start up with default settings and use UI to switch debug-view to wireframe mode.

Error message:
