RFR: 8374767: Amend JDK-8374521 with new option name

[Aleksey Shipilev]

During [JDK-8374521](https://bugs.openjdk.org/browse/JDK-8374521) review we agreed on the new option name, but I forgot to push the commit that actually does it! So we integrated [JDK-8374521](https://bugs.openjdk.org/browse/JDK-8374521) with older option name. This should amend the change with proper option name.

The options are now:


  --with-native-debug-symbols-level
                          set the native debug symbol level (GCC and Clang only) [toolchain default]
  --with-native-debug-symbols
                          set the native debug symbol configuration (none,
                          internal, external, zipped) [varying]


Additional testing:
 - [ ] GHA
