8364199: Enhance list of environment variables printed in hserr/hsinfo file

[MBaesken]

We have a number of interesting environment variables influencing the JVM/JDK that could be added to the list of environment variables printed in the hserr/hsinfo file.
JAVA_OPTS is used by lots of tools .
WAYLAND_DISPLAY (

jdk/src/java.desktop/unix/classes/sun/awt/UNIXToolkit.java

Line 492 in 965b681

final String display = System.getenv("WAYLAND_DISPLAY");

)
and JDK_AOT_VM_OPTIONS (

jdk/src/java.base/share/man/java.md

Line 4052 in 965b681

Extra JVM options can be passed to the second JVM process using the environment

) are referenced in the codebase.
