[jdk11u-dev] RFR: 8283606: Tests may fail with zh locale on MacOS

[Nagata-Haruhito]

I would like to backport JDK-8283606 to JDK11u. This fix cannot be applied cleanly.
- Test does not provided in JDK11u
  (test/langtools/jdk/javadoc/tool/testLocaleOption/TestLocaleOption.java)
- Need to add test items that is removed from the following test in the latest version
  (test/langtools/jdk/javadoc/tool/EnsureNewOldDoclet.java)
- Need to add more tests that are removed in latest version and have same problem.
  (test/langtools/tools/javadoc/6964914/TestStdDoclet.java,
   test/langtools/tools/javadoc/6964914/TestUserDoclet.java, and
   test/jdk/tools/pack200/DeprecatePack200.java)

I tried to run these tests on Japanese Windows 10, and all tests are passed.

But, I am not a author, so need a sponsor.
Would you plese review this fix?

Thank you.
