emulators/wine-devel: update to Wine 7.21
This includes the following changes:
- OpenGL library converted to PE.
- Support for multi-architecture PE builds.
- More preparation work for Vulkan 32-on-64 support.
- Support for creating import libraries without dlltool.
- Locale data updates.
- Various bug fixes.
Additionally, OpenAL has been removed as a dependency, as upstream
no longer provides it either.
