[SYCL][ClangLinkerWrapper] Rework the testing of SYCL Offload Wrapping in clang-linker-wrapper
The patch allows to test SYCL Offload Wrapping using clang-linker-wrapper in dry-run mode. Previously, it was tested by running the tool in non dry-run mode. The patch unites 2 debuging prints of "offload wrapper" step in clang-linker-wrapper in Verbose/DryRun modes. The patch returns the test case in linker-wrapper-sycl.cpp that has been removed in intel#17546.
