[master] RFR: Merge jdk:jdk-24+9 [v2]

[Roman Kennke]

> Merges upstream tag merge-jdk-24+9 such that the repo is identical to that tag afterwards. I.e. we discard all changes from the lilliput repo, because JEP-450 has been upstreamed and that subsumes all work that we have maintained here.
> 
> The plan is to shift this repo to development work on Lilliput-2 ('4-byte-headers').
> 
> Ok?
