Move mempcpy, strcpy and stpcpy inlines to string/string-inlines.c as compatibility
symbols as they are no longer used. Fix compat symbols for __strpbrk inlines.

        [BZ #18712]
        * string/string-inlines.c (__STRING2_COPY_TYPE): Add, moved from string2.h.
        (__old_mempcpy_small): Likewise.
        (__old_strcpy_small): Likewise.
        (__old_stpcpy_small): Likewise.
        (__old_strpbrk_c2): Fix compat symbol name.
        (__old_strpbrk_c3): Likewise.
        * string/bits/string2.h (__STRING2_COPY_TYPE): Remove.
        (__mempcpy_small): Remove.
        (__strcpy_small): Remove.
        (__stpcpy_small): Remove.
