[WFCORE-6661] More accurate, resettable start time calculation

[bstansberry]

https://issues.redhat.com/browse/WFCORE-6661

This encapsulates the existing and possible future (WFCORE-6657) behavior around calculating and resetting 'start time' in a class, instead of passing around primitive 'startTime' longs and doing math. It uses RuntimeMXBean for the original 'start time' of a non-embedded process, instead of using Module.getStartTime(), which is a time when JBoss Modules started, not when the JVM did.

Hello @bstansberry are you interested in getting this for WF23?

[bstansberry]

@yersan Thanks for asking. No, this not urgent and shouldn't go in WF 31. It's a small foundation piece that's important for my prototyping at https://github.com/bstansberry/wildfly-core/commits/WildFly_CRaC, but that is just a research project. It's valid on it's own (it uses a more accurate JVM start time) so I went ahead and sent up the PR, but that benefit is quite minor and is not enough to justify doing it so late in the 31 work.
