The code that sets these up is in unicode-letters.tex, which is read  
during the creation of the default xetex and xelatex formats. You can  
easily write a loop that simply resets the classes of all the  
characters to 0, and override the \XeTeXinterchartoks commands in that  
file with null versions if you wish.

(That code really should be updated to use \newXeTeXintercharclass and  
symbolic names, anyway....)
