Changes

• Conformance Tests
• Fix: Change conformance_layer debug utils callback return value to XR_FALSE to match specification requirements. (internal MR 4032)
• Fix: Allow default Metal device to be created when xrGetMetalGraphicsRequirementsKHR has not been called, to test the error case similar to other graphics plugins. (internal MR 4039)
• Fix: Skip "XR_FB_space_warp" test when no suitable swapchain format is available. (internal MR 4040)
• Fix: Correctly define XR_EXT_dpad_binding paths for /interaction_profiles/bytedance/pico_ultra_controller_bd in XML, affecting generated tests. (internal MR 4049)
• Fix: Copy vulkan layer json with conformance_cli. (internal MR 4062)
• Improvement: Clean up handle state creation and usage in the CTS layer, passing handle state to hook implementations to reduce repeated mutex locking. (internal MR 3809, OpenXR-CTS PR 101, internal MR 3808, OpenXR-CTS PR 108)
• Improvement: Handle graphics plugin ShutdownDevice() calls in most cases with a scope guard. (internal MR 3941)

• Improvement: Add self test for CTS, using the "do-nothing" test_runtime. (internal MR 3989)
• Improvement: Set Visual Studio working directory for conformance_cli (internal MR 4059)
