feature request: detect availability of some tools like "zip" and handle its absense with meaningful error message

[leha-bot]

Sometimes on fresh linuxes (in VM/WSL/docker) some utilities required for vcpkg could ne absent and vcpkg would fail silently. For example:

error: zip --quiet -y -r /home/user/proj/vcpkg/packages/vcpkg-cmake_x64-linux.zip * --exclude .DS_Store failed with exit code 127
sh: 1: zip: not found
