Implemented fatal:u properly (#1347)
* Implemented fatal:u properly fatal:u now is properly implemented with all the ipc cmds. Error reports/Crash reports are also now implemented for fatal:u. Crash reports save to yuzu/logs/crash_reports/ The register dump is currently known as sysmodules send all zeros. If there are any non zero values for the "registers" or the unknown values, let me know! * Fatal:U fixups * Made fatal:u execution break more clear * Fatal fixups
