arm64, loongarch64, and sw64 architectures

- Add support for V25 GRUB theme adjustments
- Migrate the original deepin theme resources to the deepin-v20
directory
- Copy a theme from deepin-fallback to the deepin theme
- Upgrade the theme adjustment tool version from 18 to 19
- Specifically increase the menu width when GFXMODE is set to
1024x768
