Revert "[Driver][SYCL] Add compile-time device library linking for SPIR-V targets" (#212550)

Reverts llvm/llvm-project#196656
The CI does not yet build compiler-rt with SPIR-V support, so
libclang_rt.builtins.bc is absent on that bot. This change made the
missing file a hard error, breaking all libsycl functional tests that
compile with -fsycl.

Re-landing after CI is updated to build compiler-rt for SPIR-V.
