Vulkan: Fix accessing index buffer with uninitialized memory This was discovered by Clusterfuzz on MacOS. The issue was that is index buffer of a draw indexed call was missing, causing SwiftShader to access uninitialized memory, leading to the ASAN crash. The missing index buffer was caused by DIRTY_BIT_INDEX_BUFFER not being set. This was in turn caused by ContextVk::flushDirtyGraphicsRenderPass() not setting dirty bits not included in the dirtyBitMask, despite needing to be set for future processing.
