Vulkan: Optimize Attribute Change Perf (4/5)

This patch series optimizes programs that use the pattern: for (;;) { glVertexAttribPointer(...) glDraw(...) } Change 4: Inline ValidateProgramDrawStates. A hotspot in most draw calls that change state. In total the patch series reduces test iteration time by 25%. This change reduces the listed "null" benchmark time from 295 -> 286 ns. Test: DrawCallPerfBenchmark.Run/vulkan_null_attrib_change Bug: angleproject:5045 Bug: b/168493024 Change-Id: I80959c9d06030709d7f4eba696e43614c33d5a8f Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2409176 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: 's avatarCourtney Goeltzenleuchter <courtneygo@google.com> Reviewed-by: 's avatarShahbaz Youssefi <syoussefi@chromium.org>
