Self-built ANGLE bundle for Q2PRO-X `win32egl` backend.

Purpose:
- portable runtime for Windows `win32egl`
- fixes NVIDIA App recording corruption seen with `win32wgl` on this machine

Files bundled next to `Q2PRO-X.exe`:
- `libEGL.dll`
- `libGLESv2.dll`
- `d3dcompiler_47.dll`

Built from:
- ANGLE checkout: `O:\Claude2\angle_checkout`
- output dir: `O:\Claude2\angle_checkout\out\ReleaseMsvc`

Build notes:
- built locally on Windows with MSVC toolchain
- standalone build required a local fallback shim for missing Chromium helper binaries in the checkout
- previous temporary Chrome-derived DLLs were preserved as:
  - `libEGL.chrome-test-backup.dll`
  - `libGLESv2.chrome-test-backup.dll`

Q2PRO usage:
- `vid_driver win32egl`
- restore old backend with `vid_driver win32wgl`
