chore: Add MIT License and fix Windows platform support

- Add MIT License file for open source release
- Update README.md to reference LICENSE file
- Fix test_bgfx_triangle.cpp: Add Windows platform support (_WIN32)
- Fix test_bgfx_sprites.cpp: Add Windows platform support (_WIN32)

These visual tests now support both Windows (wmi.info.win.window)
and Linux (wmi.info.x11.window) platforms.
