Description

The previous fuzzing code is obsolete now. Other languages have finished moving to new fuzzing platform. Only several classes are still used from the old module. Therefore, old module is renamed from utbot-fuzzer to utbot-java-fuzzing to clarify that is used only for java-specific fuzzing. Though, there are several things to do:

1. Things like FuzzedValue, FuzzedType, etc. should be replaced by own implementations in specific languages (to get rid off classId transitive dependency).
2. UtFuzzedExecution should be moved to some new place. This problem should be discussed with @EgorkaKulikov because summarization depends on it.

How to test

Automated tests

All fuzzing-related tests should pass as before.
