📄 Description

Fixes/works around #1704

Seems like enabling userfaultfd either causes various crashes on boot or mid-game.

Let's make it opt-in for now, until that is resolved.

https://github.com/shadps4-emu/shadPS4/issues/1704#issuecomment-2526263846 suggested to bake it as a CMAKE flag instead of a hardcode disable, so this PR was changed to do this.
