RFR: 7903774: make all tests combinations printing nicer and/or configurable [v8]

[Jiří Vaněk]

> This is still WIP, but already on row what [CODETOOLS-7903774](https://bugs.openjdk.org/browse/CODETOOLS-7903774) suggested.
> 
> It will be finished once all desired output combinations are included, but already now is doing the usage of listing much more comfortable and code readable.
> 
> From:
> 
> `TESTS` - as introduced by https://github.com/openjdk/jcstress/pull/149
> `COMBINATIONS` - as introduced in https://github.com/openjdk/jcstress/pull/149 verbose mode (thus surpassing the `-v` impact
> `ALL_TESTS` - all tests as it was before https://github.com/openjdk/jcstress/pull/149
> `COMBINATIONS_GROUPED ` - as suggested in https://github.com/openjdk/jcstress/pull/149#discussion_r1668678910
> `COMBINATIONS_JSON` same as combinations, but a valid json
> `COMBINATIONS_GROUPS` same as COMBINATIONS_GROUPED only instead of enumeration in each group, only count of members will be printed 
> 
> 
> * TESTS are already implemented as ALL_MATCHING
> * COMBINATIONS as ALL_MATCHING_COMBINATIONS
> * ALL_TESTS as ALL
> 
> COMBINATIONS_GROUPED, and COMBINATIONS_GROUPS are under development.
> The _JSON variants are tobe decided, but ability to JQL it sounds nice.
> 
> Suggestion to better names welcomed.

Jiří Vaněk has updated the pull request incrementally with one additional commit since the last revision:

  Added property to control json variants fragemnts
  
  if true, the key will be written as:
  "[actor1, actor2], spinLoopStyle: Thread.onSpinWait(), threads: 2, forkId: 0, maxFootprintMB: 64, compileMode: 7, shClass: (PG 0, CG 0), (PG 0, CG 0), strideSize: 256, strideCount: 40, cpuMap: null, [-XX:+UseBiasedLocking, -XX:+StressLCM, -XX:+StressGCM, -XX:+StressIGVN, -XX:+StressCCP, -XX:StressSeed=yyyyyyyy]"
  
  otherwise (default), it will be written as
  
  ...
  "actorNames": ["actor1", "actor2"],
  "spinLoopStyle": "Thread.onSpinWait()",
  "threads": 2,
  "forkId": 0,
  "maxFootprintMB": 64,
  "compileMode": 7,
  "shClass": "(PG 0, CG 0), (PG 0, CG 0)",
  "strideSize": 256,
  "strideCount": 40,
  "cpuMap": "null",
  "jvmArgs": [-XX:+UseBiasedLocking, -XX:+StressLCM, -XX:+StressGCM, -XX:+StressIGVN, -XX:+StressCCP, -XX:StressSeed=yyyyyyyy]"
