Add option ROCM_EXAMPLES_ENABLE_HIPDNN when buildling rocm-examples to give users option to not build any hipDNN tests. hipDNN requires gcc13 to build tests for it.

[pbhandar-amd]

Motivation

hipDNN requires users to have gcc 13 installed on the machine. If they don't have this installed, rocm-examples will fail to compile on the amd-staging branch due to the error below. Users should be able to disable hipDNN tests from building if they don't have gcc13 installed so that they can still build rocm-examples.

Technical Details

Test Plan

I was able to build rocm-examples by setting -DROCM_EXAMPLES_ENABLE_HIPDNN="OFF" and DROCM_EXAMPLES_ENABLE_HIPDNN="ON"

Test Result

Was able to build and run rocm-examples.
