    Fix __builtin_nested_func_ptr_{created,deleted} symbol versions [PR113402]

    The symbols for the functions supporting heap-based trampolines were
    exported at an incorrect symbol version, the following patch fixes that.

    As requested in the PR, this also renames __builtin_nested_func_ptr* to
    __gcc_nested_func_ptr*.  In carrying our the rename, we move the builtins
    to use DEF_EXT_LIB_BUILTIN.

            PR libgcc/113402

    gcc/ChangeLog:

            * builtins.cc (expand_builtin): Handle
BUILT_IN_GCC_NESTED_PTR_CREATED
            and BUILT_IN_GCC_NESTED_PTR_DELETED.
            * builtins.def (BUILT_IN_GCC_NESTED_PTR_CREATED,
            BUILT_IN_GCC_NESTED_PTR_DELETED): Make these builtins LIB-EXT and
            rename the library fallbacks to __gcc_nested_func_ptr_created and
            __gcc_nested_func_ptr_deleted.
            * doc/invoke.texi: Rename these to __gcc_nested_func_ptr_created
            and __gcc_nested_func_ptr_deleted.
            * tree-nested.cc (finalize_nesting_tree_1): Use builtin_explicit
for
            BUILT_IN_GCC_NESTED_PTR_CREATED and
BUILT_IN_GCC_NESTED_PTR_DELETED.
            * tree.cc (build_common_builtin_nodes): Build the
            BUILT_IN_GCC_NESTED_PTR_CREATED and BUILT_IN_GCC_NESTED_PTR_DELETED
local
            builtins only for non-explicit.

    libgcc/ChangeLog:

            * config/aarch64/heap-trampoline.c: Rename
            __builtin_nested_func_ptr_created to __gcc_nested_func_ptr_created
and
            __builtin_nested_func_ptr_deleted to __gcc_nested_func_ptr_deleted.
            * config/i386/heap-trampoline.c: Likewise.
            * libgcc2.h: Likewise.
            * libgcc-std.ver.in (GCC_7.0.0): Likewise and then move
            __gcc_nested_func_ptr_created and
            __gcc_nested_func_ptr_deleted from this symbol version to ...
            (GCC_14.0.0): ... this one.
