RFR: 8263549: 8263412 can cause jtreg testlibrary split [v3]

[Igor Ignatyev]

> Hi all,
> 
> could you please review this dull patch that replaces `ClassFileInstaller` w/ `jdk.test.lib.helpers.ClassFileInstaller` in all jtreg test descriptions to ensure we won't get split testlibrary, and removes `jdk/test/lib/ClassFileInstaller.java` (so it won't be accidentally used).
> 
> from JBS:
>> after JDK-8263412, we might (again) encounter NCDFE b/c parts of testlibraries aren't on the classpath. this happens when jtreg builds `jdk.test.lib.helpers.ClassFileInstaller` as a part of test-specific code, but `ClassFileInstaller` as part of shared testibrary directory in one test, when in the following test, jtreg sees `ClassFileInstaller` in the shared directory, hence javac won't recompile it/its dependencies, but in runtime `jdk.test.lib.helpers.ClassFileInstaller` is nowhere to be found, hence we get NCDFE. 
> 
> testing:
> - [x]  `grep ' ClassFileInstaller[^.]`
> - [ ] tier1-3
