When CCS compression first came out on Skylake, we referred to it as "renderbuffer compression", or RBC for short. However, that name has long since fallen out of favor, and we refer to it as CCS nearly everywhere. This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc name continues to work, because it's one line of code and having both names makes our lives easier in the interim.
