[SYCL][NFC] SYCL RT CMakeLists cleanup [2/N] (#17388)

This is one patch in a series intended to re-organize
`add_sycl_rt_library` helper function to make it shorter and simpler.

Dropped unnecessary `target_include_directories` calls:
- `LIB_NAME` is a link-only target, no need to set any include
directories for it
- SYCL RT should not be using `unified-runtime/source` or
`unified-runtime/source/common` includes
