Add a dynamic blending sample for VK_EXT_extended_dynamic_state3

[Krzysztof-Dmitruk-Mobica]

Description

This PR proposes the sample demonstrating dynamic blending functionality of the VK_EXT_extended_dynamic_state3 extension. Functions used are: vkCmdSetColorBlendEnableEXT, vkCmdSetColorBlendEquationEXT, vkCmdSetColorBlendAdvancedEXT, vkCmdSetColorWriteMaskEXT.

Notes

Tested on:

Ubuntu 23.04
Intel i7-11800H
Intel TigerLake-H GT1/Nvidia T600 Mobile
32 GB RAM

Arch Linux/Windows 11
AMD Ryzen 2600
Nvidia GTX 1070
16 GB RAM

This PR uses non-final version of the color edit implementation from my other PR. I intend to fix it when the status of the other PR is clarified.

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• I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)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

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 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

Nice!
Just a couple of (mostly) minor issues.

I can't test this one unfortunately since we don't support dynamic ColorBlendAdvanced.
Just wondering if the sample could actually not require that, but just use it if available?

Thank you very much for this sample 👍

Runs fine for me. I only found a very small typo in the readme, so I'll give this an approval :)

I just realized, I didn't submit my review, yet!
Done now.
