Fix RHI documentation discrepancies and add missing doc files

Fixed incorrect links in OpenGL documentation:
- Fixed wrong links to threading/task-system docs for Initialize/Shutdown methods
- Fixed wrong links to buffer docs for GetNativeHandle methods
- Fixed wrong links to shader docs for Bind/Unbind methods
- Fixed wrong links to command-list docs for Clear/Reset/Close methods
- Fixed wrong links to buffer/get-size.md for width/height methods

Added missing documentation files:
- OpenGL buffer: bind.md, unbind.md, get-type.md, initialize.md
- OpenGL fence: initialize.md, reset.md
- OpenGL swap-chain: get-size.md, initialize.md
- OpenGL render-target-view: initialize.md, shutdown.md, bind.md, unbind.md, clear.md, get-size.md
- OpenGL depth-stencil-view: initialize.md, shutdown.md, bind.md, unbind.md, get-size.md
- OpenGL command-list: clear.md

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