[jdk11u-dev] RFR: 8299635: Hotspot update for deprecated sprintf in Xcode 14

Backport of [JDK-8299635](https://bugs.openjdk.org/browse/JDK-8299635) as applied to JDK-17, in order to get building on macos-13/Xcode 14/clang 14.

Mostly clean but for these files:


src/hotspot/os/aix/os_aix.cpp
src/hotspot/os/linux/os_linux.cpp
src/hotspot/share/opto/cfgnode.cpp
src/hotspot/share/opto/chaitin.cpp
src/hotspot/share/opto/chaitin.hpp
src/hotspot/share/opto/type.cpp


In `src/hotspot/share/opto/type.cpp` we restored JDK-17's `nullptr` back to JDK-11's `NULL`.

After this PR the macos-builds are expected to continue failing with error messages similar to:

A) The `-Wdeprecated-non-prototype` flag. This seems JDK-11 specific as these files were later reorganized in next JDK versions. We may need a JDK-11 specific issue for this compilation failure.

B) Some missing `sprintf` in files in the `src/jdk.pack` directory, which is JDK-11 specific as Pack200 was removed in later versions.
