Add fixes for COJ Gunslinger on Steam

[Tiagoquix]

• Add wmp11 to fix cutscenes
• Limit to 31 cores

Please let me know if I missed something. Thanks!

wmp11 and 31 cores fixes are due to user reports:

ValveSoftware/Proton#366

It seems like both wmp9 and wmp11 work, so we should prefer the newer version.
I am using wmp11 and it works normally.

The first statement is not strictly necessary when it comes to applying fixes, so users shouldn't need to worry about it.

As for the second statement, it depends but you will most likely need it to do anything useful since all the functionality to apply a fix are currently in that file.
