MkDev11 061145e67b [2.x] Add testForkedParallelism setting for forked test thread count (#8453)
**Problems**

When running forked tests, sbt uses `Runtime.getRuntime().availableProcessors()` to determine the thread pool size, ignoring `concurrentRestrictions`. This is inconsistent with non-forked parallel tests.

**Expectations**

Users should be able to control the number of parallel test threads in forked mode, similar to how `concurrentRestrictions` works for non-forked tests.

**Notes**

Added a new setting `testForkedParallelism` that allows explicit control:

```scala
testForkedParallelism := Some(2)  // Use 2 threads
testForkedParallelism := None     // Use availableProcessors() (default)
```
