[FEATURE] JDK 24 Compatibility

[mmoayyed]

Describe the feature

Allow lombok to support building against JDK 24.

Describe the target audience

While JDK 24 is still in EA mode as of this writing, there are EA builds available nonetheless that one can use for experimentation and preparation against the next JDK release.

Additional context

Lombok likely requires a new version of the lombok patcher to support the new Opcodes.V24 constant for Java 24.

Please see projectlombok/lombok.patcher#17

JDK 24 is now in RampDown phase. This means that it's safe to get this finalized.

It would be really great if Lombok is, for the first time, compatible with the new JDK before its release date.

ASM is already compatible.

Rampdown doesn't mean that there are no breaking changes in the compiler. As far as I know we only have to adjust one small thing besides the mandatory ASM update.

While technically it could be broken, but only for "extraordinary" issues.
I would say my statement above is correct, that it's safe for Lombok to finalize JDK 24 features.

And thank you for your work on Lombok!
