sim: common: add PRI printf defines

Browse source 
Keeping track of the right printf formats for the various types can be
a pretty big hassle, especially in common code which has to support a
variety of bitsizes.  Take a page from the existing standards and add
a set of PRI macros which hide the details in a common header.
