Consult hipTensor to determine if an arch is supported when building their examples

[evedovelli]

Motivation

Avoid inconsistency between list of officially supported architectures by hipTensor and the accepted list of architectures when building the examples.

Technical Details

Use a new cmake function provided by hipTensor instead of verifying the architecture against a locally maintained list of supported architectures.

Depends on ROCm/hipTensor#409

Test Plan

1. rocm-examples built with CMAKE_HIP_ARCHITECTURES including only hipTensor supported architectures.
2. rocm-examples built with CMAKE_HIP_ARCHITECTURES including hipTensor non-supported architectures.

Test Result

1. Build including hipTensor examples, as expected.
2. Build not including hipTensor examples, as expected.

Thanks so much for this change! Can you also change all the subfolders' CMake files that was modified in #324?

Thanks! LGTM

Thanks for approving @zichguan-amd!

The rocm-examples is currently failing for this PR because the rocm version installed as dependency doesn't yet include my updates in hipTensor. I'll wait till the hipTensor changes are visible before merging this PR.
