[MIGraphX EP][ROCm EP] Update build args to include rocm_gfx_arch input for ROCM/MIGraphX EP builds

[TedThemistokleous]

Description

Allow for us to select GFX targets for build

Motivation and Context

Used by our QA but also can be leveraged by third parties to try builds for specific gfx targets and architectures

Already in our rocm7.0 testing branch via : https://github.com/ROCm/onnxruntime/pull/126

@TedThemistokleous, could you create a new python environment to run lintrunner?

[TedThemistokleous]

Sure, is there a specific python version you want this to run in? I'm just using baseline ubuntu with python 3.12

You can try python 3.10.

closing this, not needed anymore as this was more a component related to CK support via ROCm EP build path. MIGraphX should have prebuilt support already for gfx arch
