RFR: 8350136: Create release notes for JavaFX 24 [v2]

[Kevin Rushforth]

> This PR adds the release notes for the JavaFX 24 release. This will first go into master, and then be backported to the jfx24 branch so it will be available in that branch when JavaFX 24 is published (and from there also synced into the jfx24u repo).
> 
> The following filter was used to produce the list of issues fixed in JavaFX 24:
> 
> https://bugs.openjdk.org/issues/?filter=46704
> 
> Additionally, we had seven issues with a release-note=yes label, which are included in the list of important changes, etc (one of them is still pending the text for the release note).
