Failed assertion 'IOGPUMetalCommandQueue: command queue residency set limit of 32 exceeded' in VK CTS

[dboyan]

Recent version of MoltenVK will crash some vulkan CTS test with the failed assertion as shown in the title. An example test to trigger the failure is dEQP-VK.api.object_management.multithreaded_shared_resources.device.

The usage of residency set is introduced in #2402, seems that this is problematic. Reverting the merge resolves the problem.

PR #2452 fixs this.
