[KSP2] Wrong internal method name with custom moduleName compiler option

Steps to reproduce:
Specify `moduleName` in Android module `:app`:
```
kotlin {
    compilerOptions {
        moduleName = "foobar"
    }
}
```

In that case KSP2 will use default `app_debug` for internal methods instead of `foobar_debug` and Java compilation will fail.
KSP1 works correctly.
