Update base for Update on "[ET-VK] Consolidate shader compilation into one vkCreateComputePipelines call"

We target the QC Adreno driver implementation of Vulkan. The Vulkan API does not enforce how QC actually uses the cache. As the plural naming of `vkCreateComputePipelines` suggests, we observed that the `createInfoCount`, `pCreateInfos` and `pPipelines` arguments above allow construction of multiple compute pipelines in one invocation. We refactor ET-VK to accumulate metadata necessary for pipeline construction and invoke vkCreateComputePipelines only once. QC's implementation maximizes the cache if we create the same number of compute pipelines in fewer invocations of vkCreateComputePipelines. This decreases model load for a sample model from 1.7s to 200ms.
