RFR: 8368781: PerfMemory - make issues more transparent [v8]

[Matthias Baesken]

> Currently issues with perfMemory like problems with the secure tmp subdirectory creation are not very transparent in release JVMs.
> 
> There exists some warnings traces but they are behind develop flags like Verbose so only available in debug JVMs.
> We could (in case of issues) store some information and write it later into hsinfo/hserr files ; or make the existing warnings available too in release JVMs.
