DSPHLE: Added an option for 48khz output and supporting upsampling code.

Browse Source 
Games that have higher frequency sounds and music should sound a bit better using 48k. 

I don't have any games that use DTKMusic so that upsampling code untested. If you get strange sounds only at 48k try toggling dtk music to see if that isolates the problem and let me know.
