RFR: 8372245: GTest globalDefinitions.format_specifiers cannot run without VM [v2]

[Axel Boldt-Christmas]

> globalDefinitions.format_specifiers uses `ResourceMark` which requires a created VM.
> Either we stop using resource allocations, or we run the test in VM.
> 
> I propose we let this test simply use `stringStream::base` rather than `stringStream::as_string` which is an already managed string and the stream is in scope for as long as the string is used. The string is guaranteed to be valid as long as we do not write to the stream.

Axel Boldt-Christmas has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains two commits:

 - Merge branch 'JDK-8372241' into JDK-8372245
 - gtest globalDefinitions.format_specifiers cannot run without VM
