[SYCL][NFC] Detach unit-tests naming from UR
This is a follow-up from #14145. Our unit tests have mock classes corresponding to device images and other entries our compiler generates. They are all named using Ur prefix, but they have nothing to do with Unified Runtime, they are part of our compiler interface.
This patch renames associated files and classes so they do not refer to Ur anymore.
This is a mechanical find-and-replace change.
This PR will conflict with #14816. I have no strict preference about which one goes first, but I think that if we merge this one first, then I will have less conflicts to resolve.
then I will have left conflicts to resolve.
Is that s/left/less/ ?

Yes

I've verified locally that build and unit-tests still pass after merge with sycl branch, so I will proceed with this PR.
