Fix depth-stencil image aspect masks

[swayam8624]

Summary

• derive the depth image aspect mask from the selected depth format
• use the mask for the image view and both layout-transition barriers

Root cause

The tutorial can select a depth/stencil format such as VK_FORMAT_D32_SFLOAT_S8_UINT, while the attachment sample hardcodes VK_IMAGE_ASPECT_DEPTH_BIT. Validation then reports VUID-VkImageMemoryBarrier2-image-03320 because the stencil aspect is omitted.

Validation

• Reproduced on macOS Apple Silicon (M2 Pro) with the Khronos validation layer.
• cmake -S attachments -B build/tutorial -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_OSX_ARCHITECTURES=arm64 -DENABLE_CPP20_MODULE=OFF -DKTX_INCLUDE_DIR=... -DKTX_LIBRARY=...
• cmake --build build/tutorial --target 32_ecosystem_utilities -j4
• standalone C++20 syntax check passed with Vulkan-Hpp defines
• git diff --check passed

The executable initializes Vulkan but exits in this checkout because the required tutorial asset file is not found from the build layout.

An important fix.
Just one issue:

[asuessenbach]

Instead of the potentially being removed Renderer::hasStencilComponent (see #427), you might use the more general vk::hasStencilComponent from vulkan_format_traits.hpp.

[swayam8624]

Addressed in commit f2b8e25. I added the explicit vulkan/vulkan_format_traits.hpp include, replaced the attachment-local helper with vk::hasStencilComponent, and removed the duplicate helper. The 32_ecosystem_utilities target builds successfully on macOS arm64.
