Vulkan: Disable push descriptors on older NVIDIA GPUs (#6340)

Disables push descriptors on older NVIDIA GPUs (10xx and below), since it is clearly broken beyond comprehension. The existing workaround wasn't good enough and a more thorough one will probably cost more performance than the feature gains. The workaround has been removed.

Fixes #6331.
