Allows the tests to set the exact values vk-bootstrap will receieve rather than require a real vulkan driver to be present on the system. This is done by creating a `vulkan-1.dll` on windows that implements all of the API functions, and on linux/macOS intercepts `dlsym` to make it return the mock's functions.
