[SPIRV] Support for SPV_EXT_fragment_shader_interlock #3564

Description of Feature

I am trying to use RenderDoc to debug my implementation of Moment-Based OIT which takes advantage of ROVs and fragment shader interlock. In the current state of RenderDoc, I am able to check the state of the storage images before and after draw calls. I would like to be able to step through my shaders that use the ROVs and fragment interlocked sections. Without changing my existing shaders to not use this functionality, it is not possible to debug the fragment shaders using this functionality.

I would like support for the various OpExecutionModes provided by SPV_EXT_fragment_shader_interlock within the shader debugging functionality.

Environment

• RenderDoc version: 1.37
• Operating System: Windows 11 (Build 22631)
• Graphics API: Vulkan 1.3
