[PR other/65021] mkoffloads -save-temps handling, and cleanup cleanup

        gcc/
        PR other/65021
        * config/i386/intelmic-mkoffload.c (mkoffload_atexit): Rename
        function to...
        (mkoffload_cleanup): ... this.  Adjust all users.
        (maybe_unlink): Look at save_temps and verbose flags instead of
        debug flag.
        (main): Parse "-save-temps" flag.
        (generate_target_descr_file, generate_target_offloadend_file)
        (generate_host_descr_file, prepare_target_image): Pass it on.
        * config/nvptx/mkoffload.c (tool_cleanup): Implement.
        (mkoffload_cleanup): New function.
        (maybe_unlink): Look at save_temps and verbose flags instead of
        debug flag.
        (main): Instead of calling utils_cleanup, register atexit handler
        for mkoffload_cleanup.
        (main): Parse "-save-temps" flag.
        (compile_native, main): Pass it on.
        * lto-wrapper.c (compile_offload_image): Likewise.
