[24] Try building the java24 patch on JDT infra

- reconcile requirements of metadata generation
  - update the feature jar with feature.properties & license.html
  - only use binary input to generate checksums
  - use a new output directory to please the metadata generator
- add JCP disclaimer to license

Fixes eclipse-jdt/eclipse.jdt.core#3244
