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 slink:VkValidationCacheEXT object type, which is managed
similarly to the existing slink:VkPipelineCache.
The new struct slink:VkShaderModuleValidationCacheCreateInfoEXT can be
included in the pname:pNext chain at flink:vkCreateShaderModule time.
It contains a slink:VkValidationCacheEXT to use when validating the
slink:VkShaderModule.
