Virgile Bello 11ecd98ffa build: convert all solutions from .sln to .slnx ...

- migrate 15 tracked solutions; update .slnf paths, workflows, build
  files, repo-root markers, ios/android runners, .vscode, docs
- Stride.slnx: drop vestigial x86/x64/Mixed Platforms (solution is
  all-managed) and build with Platform=Any CPU; GameStudio listed first
  so it stays the default startup project
- Stride.VisualStudio.slnx: Package project first (default startup)
- samples: drop dead AppStore/Testing/Windows configs (no per-platform
  exec projects remain, only .Game + .Windows)
