JavaFX Direct3D 12 - Second EA release

[Lukasz Kostyra]

Hello openjfx-dev,

The second Early Access(EA) build of JavaFX with the Windows Direct3D 12 rendering pipeline is now available at: https://jdk.java.net/javafxdirect3d12/

Please test this bundle and share your feedback by:
- emailing openjfx-dev at openjdk.java.net or
- reporting issues via JBS[https://bugs.openjdk.org/] or at https://bugreport.java.com

This is the second EA release. The backend is feature-complete and went through a first optimization pass, but it still requires some more testing on more hardware variants before we can consider it complete. As such, with this release we also would like to call for help with performance testing the backend (more details on that will be sent in a separate email thread).

Known issues and pending tasks are captured on JBS and can be accessed using the filter provided on the Direct3D 12 EA page [https://jdk.java.net/javafxdirect3d12/]. Before reporting a new bug, please review the existing issues to avoid duplicates.

Important Notes:
1. This is a Windows-specific feature, so only a Windows-specific bundle is provided.
2. The default rendering pipeline is set to d3d12. Use "-Dprism.order=d3d" or "-Dprism.order=sw" to select one of the other pipelines for comparison testing.
3. It is recommended to use JDK 25 or later.
4. At this stage D3D12 backend is feature-complete and went through the first phase of optimization. It is worth noting that, while generally we noticed performance improvements, it might not be on par with D3D backend on every machine combo  - we already noted performance being worse on recent NVidia discrete GPUs [https://bugs.openjdk.org/browse/JDK-8370486] and are looking for solutions.
5. Issue behavior may vary across different hardware, so please provide detailed information, such as the output of "java -Dprism.verbose=true" or used hardware, when reporting or discussing issues.
6. Refer: Run HelloWorld using JavaFX SDK [https://openjfx.io/openjfx-docs/#install-javafx]

We look forward to your feedback.

Regards,
Lukasz
