RFR: 8140348: Convert TraceSafepoint to Unified Logging

[Coleen Phillimore]

Copying Mattis,  Mattis, this is the second flag to be converted to use 
the Unified Logging framework.

-XX:+TraceSafepoint was a develop mode flag but Unified Logging makes it 
available in product mode.  This may be useful to customers.  Your 
comments are appreciated, as well as comments from the openjdk community.

Thanks,
Coleen
