RFR: 8344703: Compiler Implementation for Flexible Constructor Bodies

Tue Apr 8 11:36:36 UTC 2025

This PR finalizes the Flexible Constructor Bodies feature with no semantics changes.
The main changes in this PR have to do with the various tests, which needed tweaking (e.g. to drop `@enablePreview` and fix corresponding golden files).

We might, later on, incorporate a fix for [this issue](https://bugs.openjdk.org/browse/JDK-8349754) into this PR, depending on where the specification for this feature lands.
