Vulkan: Avoid some loops in VertexArray::onBufferChanged Before this CL, VertexArray::onBufferChanged() loops over bufferBindingMask bits and calls onSubjectStateChange. In this CL, VertexArray::onSubjectStateChange is embedded into VertexArray::onBufferChanged(). DIRTY_BIT_ELEMENT_ARRAY_BUFFER and DIRTY_BIT_ELEMENT_ARRAY_BUFFER_DATA is re-arranged so that we can map bufferBindingMask directly to VertexArray::mDirtyBits. This especially useful when one buffer is bound to multiple indices in the VertexArray. This CL also removes angle::ObserverInterface from VertexArray, since it no longer observes anything. ASSERT is added in gl::Buffer::mContentsObservers to ensure it only contains BufferTexture, since vertexArray is no longer using the subject/observer.
