Common: Replace MemsetFast routines with C memset 

And associated cleanup.

On most compilers these days, it'll either inline the memset with vector
fills or rep stosq, or outline with a call to memset.

I trust the compiler is probably going to make a better decision here,
than manual SSE intrinsics.

Ends up a couple of percent faster in FMV decoding.
