Setup running native tests in release mode (#2667)

Proposed here: #2608

To run native tests in release mode, separate tasks are created by KGP for additional test runs, f.e macosArm64ReleaseTest or linuxX64ReleaseTest. By default, they will be run also on build, check and allTests tasks, so they should automatically run on TC.

Note: with Kotlin 1.9.22 the original issue (#2608) doesn't reproduce nor via running protobuf tests (which contains tests for inner classes, so I haven't added additional test from original issue), nor via running tests in integration-test module (by adding reproducer test there, not included)
