Fix Windows: taskkill self-kill + soak missing build deps

1. taskkill /IM killed the install process itself — now uses
   /FI "PID ne <self>" to exclude own process
2. Windows soak jobs missing clang, zlib, make packages — added
   to all soak-quick-windows and soak-asan-windows MSYS2 installs
3. Both dry-run.yml and release.yml fixed
