Anvil - Vulkan CTS tests fail if has_context_isolation set to false
If I hardcode "has_context_isolation" to false in anv_device.c, some CTS tests fail, for example:
Test case 'dEQP-VK.binding_model.shader_access.primary_cmd_buf.uniform_buffer.vertex.single_descriptor.offset_view_zero'.. Fail (Image verification failed)
Tested: Vulkan CTS 1.3.1 recent mesa (0308abbe) Ubuntu with kernel 5.15.0-41-generic DeviceID 0x9a49, Intel Xe Graphics TGL GT2
