[PATCH/RFC] sim: common: add PRI printf defines

- Authentication-results: sourceware.org; auth=none
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.
