Vulkan: Fix mixed descriptor pool updates.
When updating the Uniforms and Textures pools at different rates we
could trigger an ANGLE bug. We would sometimes reset and free the
currently bound descriptors. We can fix this by using separate
descriptor pools for each descriptor set.
Bug: angleproject:2678
