Uncompilable tests with JDK 17 for read Files with set static field of `jdk.internal.misc.VM`

[alisevych]

Description

Tests generated for read Files with JDK 17 are uncompilable.
Class "jdk.internal.misc.VM" is accessed to set static field "initLevel"
The class is not found in JDK 17.

To Reproduce

1. Run IntelliJ Idea Ultimate 2022.3.3
2. Install plugin IU built from unit-test-bot/rc2023.3 branch
3. Open a project with JDK 17
4. Add the following code

import java.io.File;
import java.nio.file.Files;

public class SecurityCheck {
    public int read(File path) throws IOException {
        byte[] bytes = Files.readAllBytes(path.toPath());
        return bytes.length;
    }
}

5. Generate tests with Do not mock

Expected behavior

Generated test are supposed to be compiled with project JDK.
Unneeded reflection should be avoided.

Actual behavior

There are tests Class "jdk.internal.misc.VM" is accessed to set static field "initLevel"
