SWDEV-268914 - Linux, AMF, tests fail to scale images down

This is part 2 of the change. This is for PAL backend.
The parent buffer sometimes has newer data than the sub buffer or image.
We always need to copy the data into copybuffer in pitch workaround.

Tests:
clinfo
Conformance tests: all images test, info, API, basic.
Internal runtime tests
