SWDEV-229731 - [Lnx][Rocm][Navi]Support images in full Opencl Conformance tests

1. Enable pitch workaround
2. When we use copy image, we don't need to create the custom pitch image
3. wrtBackImageBuffer_ stores device memory object, not amd image object.

Tests:
conformance kernel read / write test pass with this code change.
