This ties the caps to the compiler instance, paving the way for pre-optimizing the shared code. Most of the time, the compiler is created and owned the GPU instance, so this is fine. For runtime effects, we now use the shared (device-agnostic) compiler instance for the first compile, even on GPU. It's configured with caps that apply no workarounds. We pass the user's SkSL to the backend as cleanly as possible, and then apply any workarounds once it's part of the full program.
