Try another approach to mark hanging generated tests

[EgorkaKulikov]

Description

We mark hanging generated tests with @Timeout annotation but sometimes this annotation does not work properly.
For example, the test method for com.alibaba.fastjson.parser.DefaultJSONParser.accept sometimes significantly exceeds a timeout (see attached screen).

Visual proofs

Potential alternatives

Use another approach with assertTimeoutPreemptively
