Fix Issue [SWDEV-485618]: README Outdated: Include File

Changes to the README.md:
-Fixed the dead links in the examples.
-Updated the example to point to the ones in roctracer_spec.md instead of tests.

Changes to the roctracer_spec.md:
-Changed #include from #include <*.h> to #include <roctracer/*.h> to
reflect the latest code structure.
