## Description

This extension provides a mechanism for caching the results of potentially expensive internal validation operations across multiple runs of a Vulkan application. At the core is the VkValidationCacheEXT object type, which is managed similarly to the existing VkPipelineCache.

The new struct VkShaderModuleValidationCacheCreateInfoEXT can be included in the `pNext` chain at vkCreateShaderModule time. It contains a VkValidationCacheEXT to use when validating the VkShaderModule.
