Message : Add Vulkan mock_icd to the build Bug: angleproject:2159 Add Vulkan mock_icd from validation layer source to the standard Vulkan build. This can act as a NULL driver for Vulkan. Once the mock is built set VK_ICD_FILENAMES env variable to "<build_out_dir>/angledata/VkICD_mock_icd.json" to point loader to the mock driver and make sure the built mock icd library resides in the system's shared object search path.
