[jdk23] RFR: 8334751: revert fix for JDK-8334488 which introduced a regression

[Vicente Romero]

Fix for [JDK-8334488](https://bugs.openjdk.org/browse/JDK-8334488) which was backported from JDK 24 introduced a regression in javac. We propose to revert it. Basically code like:

class Test {
    Test() {}

    Test(int a) {
        class InnerLocal {}
        new InnerLocal() {}; //compilation fails here
        this();
    }
}

should be accepted and it is being rejected after the mentioned backport.
