RFR: 8342818: Implement JEP 509: JFR CPU-Time Profiling [v23]

[Johannes Bechberger]

> This is the code for the [JEP 509: CPU Time based profiling for JFR](https://openjdk.org/jeps/509).
> 
> Currently tested using [this test suite](https://github.com/parttimenerd/basic-profiler-tests). This runs profiles the [Renaissance](https://renaissance.dev/) benchmark with
> - ... different heap sizes
> - ... different GCs
> - ... different samplers (the standard JFR and the new CPU Time Sampler and both)
> - ... different JFR recording durations
> - ... different chunk-sizes
