Vulkan: Allow certain usecases to have non-zero stride When glVertexAttribPointer is called with a type parameter that doesn't match the vertex attribute binding's type in shader, the vulkan backend used to force the stride to 0. This is acceptable since this usecase is unspecified in spec. To allow for better app compatibility, introduce a new extension that requires normal glVertexAttribPointer functionality to be maintained if the mismatched vertex attribute type is a mismatched integer type sign. This change also modifies the VkFormat used when a mismatch in signedness occurs to use a VkFormat with the same component width as the type parameter.
