docs: Fix RHI module documentation discrepancies

Fixed incorrect links in RHI documentation:
- Fixed OpenGL swap-chain docs with wrong references to threading/containers
- Fixed OpenGL texture docs with incorrect buffer/ texture links
- Fixed OpenGL vertex-array docs with wrong threading links
- Fixed OpenGL sampler docs with wrong threading links
- Fixed OpenGL device docs with incorrect swap-chain links
- Fixed fence docs with incorrect command-queue links
- Fixed command-list docs with missing shutdown link
- Fixed get-framebuffer-size.md title mismatch

Added missing documentation:
- Created fence/wait.md
- Created command-list/shutdown.md
- Created swap-chain/resize.md
- Created OpenGL sampler initialize.md, bind.md, unbind.md
