RFR(S): 8170936: Logging: LogFileOutput.invalid_file_test crashes when executed twice.

[Kirill Zhaldybin]

Dear all,

Could you please review this fix for 8170936?

The issue was windows specific - remove() function failed to delete a 
directory on that platform.
I added delete_directory function which uses winapi RemoveDirectory 
function and also does GTest style check on its result.
I also changed TEST to TEST_VM on a few tests from the same file since 
they used ResourceMark and crashed if they were run isolated.

Thank you.
