8294316: SA core file support is broken on macosx-x64 starting with macOS 12.x

[vieiro]

A mostly clean backport of JDK-8294316 to properly parse core files in macOS 12 and later. Load commands with length zero are now discarded.

The fix doesn't affect directly to SA tests in 17, but it's being backported to 11 as this is the cause of openjdk/jdk11u-dev#2967 (comment).

Tests in 17 continue to pass in all platforms, including macos.

The change is not clean as there were merge conflicts in ProblemList.txt, as these usually differ between JDK versions.
