  Revert "[compiler-rt] Check for and use -lunwind when linking with -nodefaultlibs (#65912)"

This reverts commit 64c0bddb7639dd4bfad73fbbc909ca739b84aa10.

This seems to run into errors on some buildbots; configure errors
out like this:

    -- Looking for _Unwind_RaiseException in unwind
    -- Looking for _Unwind_RaiseException in unwind - not found
    CMake Error at /usr/share/cmake-3.25/Modules/CheckLibraryExists.cmake:71 (try_compile):
      Only libraries may be used as try_compile or try_run IMPORTED
      LINK_LIBRARIES.  Got unwind of type UTILITY.
