Fix RHI documentation discrepancies

Fixed the following issues:
- command-list.md: Shutdown linked to threading/task-system instead of local shutdown.md
- fence.md: Wait linked to threading/task-group instead of local wait.md
- factory/create-rhi-device-string.md: Claimed Vulkan/Metal support but source doesn't support them
- opengl/buffer/buffer.md: GetType linked to command-queue/get-type (wrong type)
- d3d12/device/device.md: Initialize/Shutdown linked to threading/task-system
- d3d12/command-list/command-list.md: Initialize/Shutdown/Reset/Close/Clear linked to wrong docs
- d3d12/texture/texture.md: Initialize/Shutdown linked to threading/task-system
- opengl/command-list/command-list.md: Shutdown linked to threading/task-system
- opengl/device/device.md: GetNativeHandle incorrectly linked to get-window.md

All links validated with fix_links.py - no broken references remaining.
