[jdk17u-dev] RFR: 8295470: Update openjdk.java.net => openjdk.org URLs in test code

[Goetz Lindenmaier]

I backport this for parity with 17.0.16-oracle.

Most parts applied clean. The parts that don't apply were either Copyrights or files not in 17.

patching file test/hotspot/jtreg/applications/jcstress/TestGenerator.java
Resolved Copyright. Two later changes already backported.

test/hotspot/jtreg/compiler/vectorapi/VectorMaskCastTest.java
Added by "https://bugs.openjdk.org/browse/JDK-8271515: Integration of JEP 417: Vector API (Third Incubator)" in jdk18. Omitted.

test/hotspot/jtreg/runtime/cds/DeterministicDump.java
Code to be patched added by "https://bugs.openjdk.org/browse/JDK-8253495: CDS generates non-deterministic output". Omitted.

test/hotspot/jtreg/runtime/cds/appcds/dynamicArchive/LotsUnloadTest.java
Added by "https://bugs.openjdk.org/browse/JDK-8278602: CDS dynamic dump may access unloaded classes". Omitted.

test/jdk/java/awt/Mixing/AWT_Mixing/HierarchyBoundsListenerMixingTest.java
Resolved copyright. Later change "https://bugs.openjdk.org/browse/JDK-8280988: [XWayland] Click on title to request focus test failures"
already backported.

test/jdk/javax/swing/ImageIcon/LoadInterruptTest.java
Added by "https://bugs.openjdk.org/browse/JDK-8236987: Remove call to System.out.println from ImageIcon.loadImage" in jdk19. Omitted so far.
But eventually a candidate to backport.

test/micro/org/openjdk/bench/java/util/NCopiesBenchmarks.java
Added by performance improvement "https://bugs.openjdk.org/browse/JDK-8274715: Implement forEach in Collections.CopiesList" Omitted.


Further I checked the remaining occurances of openjkd.java.net.  Most of them were omitted by this change on purpose.  Two files are in 17 that are not in 21, but one requires the old link and the other is pointless to fix. So I rather omitted them.
