Add afterInstall.ps1 and update tool paths to APPDATA

Introduces afterInstall.ps1 for post-install setup, downloading and extracting required tools to the APPDATA\WelsonJS directory. Updates code in http.js, python3.js, ovftool.js, wamr.js, and system.js to reference binaries from the new APPDATA location. Modifies setup.iss to run the PowerShell script after installation.
