Added fallback to vkCreateRenderPass

[BastiaanOlij]

Even though vkCreateRenderPass2KHR was introduced as an extension in Vulkan 1.0, support doesn't seem to be universal for it.

As we only need the updated call for Multiview and VRS, this PR adds a fallback to the old vkCreateRenderPass if the VK_KHR_create_renderpass2 extension is not available.

Fixes #66685 and fixes #67146

I wonder if that will help with #65409, which was also caused by adding VRS in d139131.
Though it's reported on distros like Fedora 36 which should have recent Mesa drivers so full support for Vulkan 1.2 or even 1.3.

@akien-mga For Vulkan 1.2 and newer this is now core functionality and should be supported as such. The only thing I wonder about is seeing this used to be an extension and we are using it through the extension for backwards compatibility, whether it now being core means they are phasing that out. We may need to specifically test for Vulkan 1.2 or newer and just check for the core function or something like that.

It's a bit hard to say without having different hardware to test.

@clayjohn I think I got all your changes..

Looks good to me!

I ran master on my old laptop which I thought may reproduce the reported crash but unfortunately the extension was supported and I couldn't reproduce the crash.
