LOG: [Clang][Driver] Enable offloadlib option for clang-cl (#162980)

--[no-]offloadlib option is used by rocm and cuda toolchain to
enable/disable device libraries in linking phase for device code. It
makes sense to re-use this option in SYCL for similar purpose and since
clang driver supports SYCL in CL compatibility mode, we also need to
enable this option in CL compatibility mode.
