[lworld] RFR: 8354728: [lworld] Langtools work to update strict implementation to latest [v2]

[Chen Liang]

> The updates to the core libraries + langtools for the latest strict field initialization spec https://cr.openjdk.org/~dlsmith/jep401/jep401-20250409/specs/strict-fields-jvms.html is ready.
> 
> Currently, since there is no VM support, testing is restricted to generation by ClassFile API/javac and inspection through ClassFile API (and javap)
> 
> Not suitable for integration yet; StrictFinalInstanceFieldsTest requires VM side's support.
