SWDEV-354050 - Runtime support for HIP non hostcall printf

Relates to https://reviews.llvm.org/D150427,

Each printf call populates buffer with following data
1. Control DWord - contains info regarding stream, format string constness and size of data frame
   (see http://gerrit-git.amd.com/c/lightning/ec/device-libs/+/857722 for more info)
2. Hash of the format string (if constant) else the format string itself
3. Printf arguments (each aligned to 8 byte boundary)
