1. Moving stress folder from hip/test/src to hip/test.
2. Adding Stream stress tests.
These stress tests create multiple streams and launches kernel on them
in multiple combinations for 100000 iterations. These tests will test
the stability of streams created using hipStreamCreate, hipStreamCreateWithPriority
and hipStreamCreateWithFlags.
3. Adding printf stress tests using simple kernels.
4. Adding printf stress tests using a complex kernel.
