Make OrtDevice generic to support plugin EP usage.

[skottmckay]

Description

Make OrtDevice generic by removing vendor specific hardcoded memory types and replacing with generic DEFAULT/HOST_ACCESSIBLE values and an explicit vendor id to differentiate.

Remove unnecessary device id from OrtMemoryInfo. The OrtDevice in OrtMemoryInfo provides this.

Motivation and Context

Support plugin EPs

Pull Request Overview

This PR makes OrtDevice generic to support plugin EP usage by removing vendor‐specific hardcoded memory types and introducing explicit vendor IDs. Key changes include updating device construction for various execution providers and allocators, revising memory type comparisons and hash functions, and exposing a new CreateMemoryInfo_V2 API.

• The device type is changed from DML (as used in other parts of the DML provider) to GPU here; please verify that this conversion is intentional for correct device identification.

OrtDevice(OrtDevice::GPU, OrtDevice::MemType::DEFAULT, OrtDevice::VendorIds::MICROSOFT, 0)

onnxruntime/core/framework/allocator.cc:184

• For DML memory info, the device type is set to GPU with vendor MICROSOFT, which differs from the ExecutionProvider construction that uses OrtDevice::DML; please ensure this inconsistency is intentional.
