Basic UI: Remove "CPU" from "x264 CPU Preset" text

I feel like people keep mistaking how x264 preset functions.  They often
associate it with their own CPU speed, and I feel the name does not help
with that issue.  I think it may be for the best to just take it out.
At best, it will keep people away from using it unless they know what
they're doing, and at worst, people at least won't be able to associate
it with their CPU as easily anymore.
