Pull Request Overview
This PR updates the D3D12Multithreading sample to support enhanced barriers, a newer Direct3D 12 feature that provides more explicit control over resource synchronization. The sample now supports both legacy and enhanced barrier modes through build configurations.
- Adds new build configurations for Enhanced Barriers and renames existing ones to Legacy Barriers
- Upgrades Direct3D 12 interfaces to ID3D12Device10 and ID3D12GraphicsCommandList8
- Implements enhanced barrier API calls with preprocessor guards for conditional compilation
