SWDEV-227201: Introduce tests for printf on hostcall

Tests that check POSIX specifiers with a single thread:
 - hipPrintfSpecifiers.cpp     : all conversion specifiers
 - hipPrintfFlags.cpp          : common flags that modify conversions
 - hipPrintfAltForms.cpp       : alternate forms ('#')
 - hipPrintfStar.cpp           : additional arguments ('*')
 - hipPrintfWidthPrecision.cpp : floating point details

Tests that check functionality on top of hostcall
 - hipPrintfBasic.cpp       : divergent calls, series of calls, return value, etc
 - hipPrintfManyWaves.cpp   : many waves printing together
 - hipPrintfManyDevices.cpp : many waves on many devices
