Move UnityLog from QoL to MAPI

[SFGrenade]

IMO, the unity logging feature could be moved to MAPI:

• using either of these
• Then maybe also not only error, but possibly for a setting (idk if they use increasing enum values tho)
  that would sidestep (and possible require changing) some mods using Modding.Logger.Log and Unity.Debug.Log next to one another.

One feature that could be added to that then as well:

• username redaction, like instead of C:\users\SFGrenade\... or /home/sfgrenade/... it could be C:\users\%USERNAME%\... or /home/$USER/...
