We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
- Add the tests mute system for the diagnostic tests
- Move the code for the test info parsing to the separate package `parsers`
- Unification of the `linked` and `not linked` spec tests
- Package structure is refactored
- Change the multiline comment format with a test information
- Actualize `PrintSpecTestsStatistic`
- Other different code improvements
