Dedicated allocation verification

Added the ability to set the VkMemoryDedicatedRequirements structure in vkGetBufferMemoryRequirements2. Note that this cl adds no support for dedicated allocations. Passes all tests in the Tests section below. Change-Id: Ib5bc2775e66e810d1ca2d52672eb2cca71e85f5e Tests: dEQP-VK.api.buffer.dedicated_alloc.* Tests: dEQP-VK.api.buffer_view.create.* Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/27290 Presubmit-Ready: Alexis Hétu <sugoi@google.com> Reviewed-by: Nicolas Capens <nicolascapens@google.com> Reviewed-by: Chris Forbes <chrisforbes@google.com> Tested-by: Alexis Hétu <sugoi@google.com> Kokoro-Presubmit: kokoro <noreply+kokoro@google.com>
