Add compute shader derivatives sample for Vulkan extension
Description
Introduce a sample demonstrating the VK_KHR_compute_shader_derivatives extension. Includes new shader, CMake, and Vulkan application files showcasing the use of derivative instructions in compute shaders with quad-based derivative groups.
General Checklist:
Please ensure the following points are checked:
- [ ] My code follows the coding style
- [ ] I have reviewed file licenses
- [ ] I have commented any added functions (in line with Doxygen)
- [ ] I have commented any code that could be hard to understand
- [ ] My changes do not add any new compiler warnings
- [ ] My changes do not add any new validation layer errors or warnings
- [ ] I have used existing framework/helper functions where possible
- [ ] My changes do not add any regressions
- [ ] I have tested every sample to ensure everything runs correctly
- [ ] This PR describes the scope and expected impact of the changes I am making
Note: The Samples CI runs a number of checks including:
- [ ] I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)
- [ ] My changes build on Windows, Linux, macOS and Android. Otherwise I have documented any exceptions
If this PR contains framework changes:
- [ ] I did a full batch run using the
batchcommand line argument to make sure all samples still work properly
Sample Checklist
If your PR contains a new or modified sample, these further checks must be carried out in addition to the General Checklist:
- [ ] I have tested the sample on at least one compliant Vulkan implementation
- [ ] If the sample is vendor-specific, I have tagged it appropriately
- [ ] I have stated on what implementation the sample has been tested so that others can test on different implementations and platforms
- [ ] Any dependent assets have been merged and published in downstream modules
- [ ] For new samples, I have added a paragraph with a summary to the appropriate chapter in the readme of the folder that the sample belongs to e.g. api samples readme
- [ ] For new samples, I have added a tutorial README.md file to guide users through what they need to know to implement code using this feature. For example, see conditional_rendering
- [ ] For new samples, I have added a link to the Antora navigation so that the sample will be listed at the Vulkan documentation site
Again, not sure what I'm supposed to see here, but I'm getting the same weird random frames on the display as I saw with relaxed_extended_instruction and some console output:

Do we have something like a template with a framework-based hello_triangle, or so, that could be used as the base to generate a new sample?
Yes, we do. The default templates that are used when you create a new sample via our scripts include rendering the UI. That's what new samples should use, as the also include other boilerplate like documentation.

@gpx1000 Maybe it's worth to recreate these very minimalistic samples (#1418, #1419, #1420, #1421) on that template?
