[code-reflection] RFR: Merge master [v2]

[Paul Sandoz]

> Merging with master, updating to Java 25, requiring 24 as a boot JDK.
> 
> All examples and HAT are also updated. All tests pass.
> 
> I found an issue with compilation of the test [TextMatrix.java](https://github.com/openjdk/babylon/blob/code-reflection/cr-examples/triton/src/test/java/oracle/code/triton/TestMatrix.java). It looks like the encoding of the code model as a method that builds the code model is reaching class file method size limits. So for now i have switched the default encoding back to `TEXT` until this is resolved.
