Paolo Bonzini requested this change to simplify the ongoing effort to allow machine setup entirely via RPC. Includes shortening the command line form cxl-fixed-memory-window to cxl-fmw as the command lines are extremely long even with this change. The json change is needed to ensure that there is a CXLFixedMemoryWindowOptionsList even though the actual element in the json is never used. Similar to existing SgxEpcProperties. Update qemu-options.hx to reflect that this is now a -machine parameter. The bulk of -M / -machine parameters are documented under machine, so use that in preference to M. Update cxl-test and bios-tables-test to reflect new parameters.
