Fixed bug 4570 - Support Vulkan Portability rather than MoltenVK specifically
Dzmitry Malyshau
Current code, search paths, and error messages are written to only consider MoltenVK on macOS as a Vulkan Portability implementation. It's not the only implementation available to the users. gfx-portability [1] has been shown to run a number of titles well, including Dota2, Dolphin Emulator, and vkQuake3, often out-performing MoltenVK in frame rate and stability (see Dolphin benchmark [2]).
There is no reason for SDL to be that specific, it's not using any MVK-specific functions other than the WSI initialization ("VK_MVK_macos_surface"). gfx-portability exposes this extension as well, and a more generic WSI extension is in process. It would be good if SDL was written in a more generic way that expect a Vulkan Portability library as opposed to MoltenVK specifically.

Support official Vulkan SDK for macOS.
This tries to load vulkan.framework or libvulkan.1.dylib before MoltenVK.framework
or libMoltenVK.dylib. In the previous version, layers would not work for applications
run-time loading the default library.

Fix high-dpi support on macOS and simplify it and iOS variant.
The detault drawableSize for a CAMetalLayer is its bounds x its scale.
So it is sufficient to set the *layer's* scale to the desired value.

Fixed typedef redefinition errors when including both SDL_vulkan.h and vulkan.h
You should always include vulkan/vulkan.h first, then include SDL_vulkan.h
