1.2.140
First tagged release of volk, matching Vulkan 1.2.140.
Notable changes since 1.1.x:
- Full support for Vulkan 1.2
- Support for VK_KHR_ray_tracing when VK_ENABLE_BETA_EXTENSIONS is defined
- volkLoadInstanceOnly can be used to only load instance entrypoints, which is slightly faster (assumes volkLoadDevice will be used before calling any device entrypoints)
