Remove unnecessary dependence (#8296)

We identified unnecessary dependencies in the tests for Proton and the
AMD analysis pass. Specifically, the `third_party/amd` directory is
processed in CMake (line 204 of the root CMakeLists.txt) before the
`triton_libs` variable is set at line 214. As a result, when the target
`TritonAMDGPUTestAnalysis` accesses `triton_libs`, it resolves to an
empty string, which seems to be a bug.


We’ve verified that whenever these two MLIR libraries are used,
specifically in `bin/CMakeLists.txt`, the corresponding targets are
always linked to `triton_libs`. Therefore, it's safe to remove the
explicit linkage to `triton_libs` in `TritonTestProton` and
`TritonAMDGPUTestAnalysis`, as it is redundant.
