Add HIP-Examples for OpenMP Hello World

[aaronenyeshi]

Many projects such as math libraries may use ROCm installed omp.h. This example shows how to compile and run a simple OpenMP app, and does not require additional includes or linking directives.

Fixes: SWDEV-257119

[aaronenyeshi]

I will replace this Makefile with a CMake build as requested by Math libs.

[aaronenyeshi]

This latest cmake file is working, I will update the README and the test_all.sh script.

This patch is ready to be reviewed.

Better add a simple kernel launching to the test.

Did you mean a simple kernel in HIP, or using AOMP?

Why is there no CI for this PR? deepcode-ci-bot doesn't really test anything relevant.

I think DevOps have been working on adding CI to these repos for awhile.
