[HIPIFY][#199][Partial fix] Fix for cudaLaunchKernel transformation

[Synopsis]
If any of kernel arguments is a MACRO its location calculation is wrong (location of its definition is actually calculated).
Thus garbage code is being produced on the place of such a MACRO starting from the end of its actual definition.

[Solution]
Add isMacroBodyExpansion and isMacroArgExpansion checks on kernel arguments.
