Ensure that compute shaders have a subgroup size that is uniform in command scope

If the pipeline was created with the VK_PIPELINE_SHADER_STAGE_CREATE_ALLOW_VARYING_SUBGROUP_SIZE_BIT_EXT
flag the SubgroupSize may vary in the shader stage but it must be uniform with command scope.

VK-GL-CTS issue: 3036

New Tests:
dEQP-VK.subgroups.multiple_dispatches.uniform_subgroup_size

Components: Vulkan
