vk-bootstrap/tests/vulkan_mock.hpp
Charles Giessen f223c8d5ae Cleanup CMake finding of Vulkan & installation code
Adds extensive integration tests that exercise the various ways of finding
the Vulkan-Headers.

vk-bootstrap should now use the Vulkan-Headers or Vulkan::Headers targets if
they were already defined (such as is the case of FetchContent), and will
look for the VulkanHeaders package and Vulkan package as a fallback, and will
FetchContent Vulkan-Headers directly if that fails.

This should make integration seamless with the various ways vulkan-headers
is acquired.

The vk-bootstrap-vulkan-headers target was dropped in favor of directly
linking to Vulkan-Headers (creating a target by that name if none exists).
