feat: implement command queue with multi-frame buffering

D3D12 Core:
- Add d3d12_command class for command queue management
- Support Direct/Compute/Copy command queue types
- Implement multi-frame buffering (frame_buffer_count=3)
- Add begin_frame/end_frame rendering cycle
- Add NAME_D3D12_OBJECT_INDEXED macro

Platform Interface:
- Add render function pointer to platform_interface
- Implement render() in Renderer

Documentation:
- Add changelog for command queue implementation
- Update D3D12 Wiki with multi-frame buffering section
- Mark command queue task as completed
