Update MoltenVK version to 1.0.29.
Based on a patch by Stefan Dösinger.
Metal cannot do signedness conversion on vertex attributes, and for good
reason. Putting a `uint4` into an `int4`, or a `char4` into a `uint4`,
would lose those values that are outside the range of the target type.
But putting a `uchar4` into a `short4` or an `int4`, or a `ushort4` into
an `int4`, should work. In that case, force the signedness in the shader
to match the declared type of the host.
Update SPIRV-Cross to pull in the corresponding change. Bump MoltenVK
version.
Fixes to create_dylib.sh to cleanup bitcode and architecture support.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.26.

Update What's New document.
MVKPipelineLayout set auxiliary buffer MSL index relative to already-calculated
push constant buffer MSL index.
MVKPipeline destructor release auxiliary buffer MTLBuffer instance.
Nudge MVK_VERSION_PATCH.
The swizzles are passed to shaders that need them using an "auxiliary
buffer", for which there must be room in the function argument table.
Code is inserted into the shaders to swizzle reads from sampled
textures--per the Vulkan spec, component mappings must only be applied
to sampled images.
Update SPIRV-Cross to pull in some fixes for handling swizzled image
data. Bump MoltenVK version.
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.
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.
Support separate specialization for each workgroup dimension.
Support zero as a specialization ID value.
Cleanup MoltenVKShaderConverterTool.
Update to latest SPIRV-Cross version.
Update MoltenVK version to 1.0.14.
Map 1D buffer view contents to 2D Metal texture.
Add MVKPhysicalDeviceMetalFeatures::maxTextureDimension element.
Set VkPhysicalDeviceLimits::maxTexelBufferElements to maxTextureDimension ^ 2.
Shaders accessing buffer view use special function to map 1D buffer view coordinates
to 2D Metal texture coordinates.
Pass maxTextureDimension to shader.
Update to latest SPIRV-Cross version for appropriate shaders.
