RFR: 8306703: JFR: Summary views [v4]

[Erik Gahlin]

> Could I have a review of an enhancement that adds a view command to jfr.
> 
> Testing: tier1, tier2 + jdk/jdk/jfr
> 
> For the change to work properly when streaming, fix of 8307738 needs to be applied.
> 
> To simplify the review, changes not relevant to the feature, but that can use classes in jdk.jfr.internal.util package, will be refactored after this change has been integrated. Possibly in JDK 22.
> 
> Thanks
