[MIGraphX EP] Set External Data Path (#21598)

### Description
<!-- Describe your changes. -->
Changes to add in Set external data path for model weight files.
Additional fixes to ensure this compiles off the latest v1.19
Onnxruntime


### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Separate weights used for larger models (like stable diffusion) is
motivation for this change set
