rhi: vulkan: Enable all core features on the device

Browse Source 
...except robustness.

Have the appropriate compile and runtime checks. This way we still
compile with any older (1.0, 1.1, 1.2) headers, and can function
at runtime with a plain 1.0 implementation. With Vulkan 1.2+ we
can start filling out the additional, version-specific (1.1, 1.2,
1.3) feature structs.
