Refactor `TestFramework` and `TestFrameworkManager` code abstractions

[EgorkaKulikov]

Description

Currently there is an ugly class TestFramework that is an abstraction for an arbitrary test framework, both jvm-based and for experimental languages. There is also a strange abstraction UnknownTestFramework for experimental languages, while there is no JvmTestFramework, so we are to override some JVM specific properties in all test frameworks.

There is also a general class TestFrameworkManager that has no framework specific abstractions.

So, we need to refactor this abstractions and segregate all JVM-specific features in JVM test frameworks.
