Set conformance version to 1.3.3.1

Since we now expose Vulkan 1.3, the acceptable values for
conformance version, according to
https://gitlab.khronos.org/Tracker/vk-gl-cts/-/blob/main/external/vulkancts/modules/vulkan/api/vktApiDriverPropertiesTests.cpp#L57,
are currently:
- 1, 3, 3, 1
- 1, 3, 3, 0
- 1, 3, 2, 0
- 1, 3, 1, 1
- 1, 3, 1, 0
- 1, 3, 0, 0

This CL sets the version to the most recent one: 1.3.3.1

Currently, SwiftShader's conformance status is:
In Review – Will be Conformant on: 22-Oct-2022
