Rename the OGA execution provider integration from MorphiZenEP to AMDGPU so it targets the AMD GPU umbrella EP (amdgpu-ep.dll) instead of loading onnxruntime_morphizen_ep.dll directly. The umbrella forwards to the HIP backend, selected via the "profile" provider option.
- Rename src/morphizen_ep -> src/amdgpu and DeviceType::MorphiZenEP -> DeviceType::AMDGPU across generators.cpp, model.cpp, the session_options dispatch table, smartptrs.h, and the cmake source glob.
- interface.cpp: register the EP as "amdgpu", load amdgpu-ep.dll (libamdgpu-ep.so), env override AMDGPU_EP_PATH. SetupProvider also mirrors provider options into ep.<name>.* session config entries since the umbrella reads them from there.
- EnsureDeviceOrtInit: the device-init dummy session reuses the AMDGPU provider options from genai_config so the umbrella can select its backend; no profile is hardcoded.
genai_config.json selects it via: "provider_options": [{ "AMDGPU": {"profile": "llm"} }]
