[jdk11u-dev] RFR: 8216265: [testbug] Introduce Platform.sharedLibraryPathVariableName() and adapt all tests.

[Goetz Lindenmaier]

I want to backport this because we see a failure on macOS 12 that will be fixed by this change.

I had to resolve a row of files:

Copyright:
  test/hotspot/jtreg/gtest/GTestWrapper.java
  test/jdk/sun/security/krb5/auto/KDC.java

Resolve @library command:
  test/jdk/tools/launcher/ExecutionEnvironment.java

This test was added in 12 only and backported with all the fixes in 8238225.
  test/jdk/tools/launcher/JliLaunchTest.java

Copyright, @library was added in backport of 8217340
  test/jdk/tools/launcher/Test7029048.java

Test not in 11
  test/jdk/vm/JniInvocationTest.java

This was also included in 8238225
  test/lib/jdk/test/lib/Platform.java
