Fix compute shader derivatives sample descriptor set update timing

Moves descriptor set writes to prepare() to ensure resources are updated before first use, addressing potential rendering issues from accessing uninitialized descriptors.
Enhance compute shader derivatives sample with practical visualization

Extends the compute shader derivatives sample to demonstrate a practical use case: gradient-based edge detection on a procedural radial pattern. Adds a two-stage rendering pipeline where a compute shader calculates spatial derivatives and gradient magnitude, writing to a storage image, then a graphics pipeline displays the result using a fullscreen triangle technique. Includes comprehensive documentation explaining derivative computation, rendering architecture, and the fullscreen triangle optimization. Requires shader storage image read/write features and shader draw parameters extension.
Revert "add shader quad control sample demonstrating VK_KHR_shader_quad_control features."

This reverts commit d9524ac.

Add compute shader derivatives sample for Vulkan extension

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.
