[OpenMP][Test][NFC] output tool data as hex to improve readibility (#152757)

Using hex format allows to better interpret IDs: 
the first digits represent the thread number, the last digits represent
the ID within a thread

The main change is in callback.h: PRIu64 -> PRIx64

The patch also guards RUN/CHECK lines in openmp/runtime/tests/ompt with clang-format on/off comments and clang-formats the directory.
