fix(render): omit DepthStencilState on depthless pipelines for Vulkan compatibility

[Eccys]

Type of change

• Bug fix
• New feature

Description

When RenderPipeline.getDepthStencilState() is non-null, 26.1/26.2's VulkanRenderPipeline.compile only compiles withDepthPipeline (configured for a VK_FORMAT_D32_SFLOAT depth attachment) and leaves withoutDepthPipeline as 0L (VK_NULL_HANDLE). When Blur.renderToFbo begins a color-only RenderPass (hasDepth = false), VulkanRenderPass.setPipeline selects withoutDepthPipeline (0L) and passes it to vkCmdBindPipeline, causing an EXCEPTION_ACCESS_VIOLATION reading 0x18.

When DepthStencilState is omitted (null), VulkanRenderPipeline.compile compiles both withDepthPipeline (using a default ALWAYS_PASS / writeDepth = false state) and withoutDepthPipeline, and GlCommandEncoder likewise disables GL_DEPTH_TEST and glDepthMask(false).

Also fixes BLUR_PASSTHROUGH using the duplicate location pipeline/blur/up instead of pipeline/blur/passthrough.

How Has This Been Tested?

Verified against 26.2 VulkanRenderPipeline / VulkanRenderPass and GlCommandEncoder, and compiled with ./gradlew compileJava.
