sebastian schoner a7c5f5f909 Allow to skip -fileopenlog for cooks ...

The file open log is a facility that automatically keeps a log of all files the process has opened and their order. This is rather expensive as it (a) also tracks failed attempts to open files and (b) it maintains a large table in memory, storing which files have already been opened (so every file is only logged once). This table can easily grow into the tens of megabytes; even on an empty project I see this taking 60MB by itself. Making this optional allows us to skip this step for UEFN cloud cooks: in these cases we're throwing that log file away anyway.
