Add fuzzer executions in parameterized tests mode

[EgorkaKulikov]

Description

Unfortunately, we can't create parameterized tests with fuzzer executions: they may require force mocking and don't know about it themselves, otherwise parameterized tests aren't able to deal with mocks.

These cause problems when we call parameterized tests generation from plugin with useFuzzing = true.

Expected behavior

The solution is to do the following in parameterized mode:

• create parameterized tests for symbolic executions
• create standard tests for fuzzer executions
