[SMSS2]: Implement SmpTranslateSystemPartitionInformation which sets a few last registry keys as part of the initialization process.
[SMSS2]: Implement SmpLoadSubsystemsForMuSession which correctly creates a session, loads win32k.sys inside of it, and then detaches from the session. Winlogon.exe is set as the initial command (but not launched), and CSRSS is fake-started.
[CSRSRV]: No longer start win32k.sys, that's not your job.
[SMSS2]: Kill most debug prints that aren't errors.
