[DML] Restore compatibility with Windows Sdk 10.0.17134.0 (#24950)
### Description
The motivation is to allow Windows 10 LTSC 2019 (currently the only LTSC
supported until 2029) to run ONNXRuntime and the DML provider.
Inspired by https://github.com/microsoft/onnxruntime/pull/24845 to
remove dxcore.dll dependency.
Currently confirmed to work in a VM.
Real tests on hardware with DML compatible devices will be performed
very soon
