Add MVKExtensionList struct to track supported and enabled Vulkan extensions within MVKInstance & MVKDevice.
Log supported and enabled Vulkan extensions for VkInstance & VkDevice.
Add error handling for descriptor sets & 3D images in VK_KHR_maintenance1 extension.
All header files load mvk_vulkan.h instead of vulkan.h for consistent use of macOS & iOS extensions.
Much of this was already supported, simply by being supported by Metal.
Of course, this support is incomplete: Metal doesn't yet allow you to
create a 2D texture view from a 3D texture.
Remove linking MoltenVKSPIRVToMSLConverter from Build Phase in favour of PreLink.
Update to Vulkan header 1.1.83.
Update to latest version of library dependencies.
Add MVKConfiguration and deprecate MVKDeviceConfiguration.
Add vkGetMoltenVKConfigurationMVK() and deprecate vkGetMoltenVKDeviceConfigurationMVK().
Add vkSetMoltenVKConfigurationMVK() and deprecate vkSetMoltenVKDeviceConfigurationMVK().
Add build setting overrides for all initial MVKConfiguration member values.
Update to MoltenVK version 1.0.19.
Update to VK_MVK_moltenvk spec version 7.
Add SPIRVToMSLConverterOptions::isRasterizationDisabled to allow pipeline
and vertex shader to communicate rasterization status.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.17.
Add MVKPhysicalDeviceMetalFeatures::layeredRendering.
Add mvkStaticCmdShaderSource() to generate static MSL shader source for commands.
Add MVKDevice::getMTLCompileOptions() to consolidate shader compilation options.
Fix watermark timing.
Upgrade MoltenVK spec version to 6.
MVKCmdClearAttachments support clearing multiple attachment layers.
MVKCmdClearImage use renderpass clear, and support clearning multiple image layers.
Rename mvkCmdClearImage() to mvkCmdClearColorImage().
MVKDevice add getFormatIsSupported() to allow devices to test for format support.
MVKFramebuffer support multiple layers.
mvk_datatypes.h support both 2D and 3D mipmap calculations and allow
mvkMTLPrimitiveTopologyClassFromVkPrimitiveTopology() in iOS.
Remove support for VK_FORMAT_B10G11R11_UFLOAT_PACK32 & VK_FORMAT_E5B9G9R9_UFLOAT_PACK32
since format components are reversed on Metal.
Move OS extension source files to new OS directory.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.16.
On iOS, only compile IOSurface support, and link IOSurface framework to
libMoltenVK.dylib, if IPHONEOS_DEPLOYMENT_TARGET is at least iOS 11.0.
Update to latest version of SPIRV-Cross.
Update MoltenVK version to 1.0.15.
