IPC refactor part 3+4: New server HIPC message processor (#4188)
* IPC refactor part 3 + 4: New server HIPC message processor with source generator based serialization * Make types match on calls to AlignUp/AlignDown * Formatting * Address some PR feedback * Move BitfieldExtensions to Ryujinx.Common.Utilities and consolidate implementations * Rename Reader/Writer to SpanReader/SpanWriter and move to Ryujinx.Common.Memory * Implement EventType * Address more PR feedback * Log request processing errors since they are not normal * Rename waitable to multiwait and add missing lock * PR feedback * Ac_K PR feedback
