scripts: template_setup_win: Use wget from host tools

The GNU Project does not distribute official binaries for wget on
Windows, and obtaining trustworthy pre-compiled wget binary on Windows
outside package managers can be difficult.

This commit updates the Windows setup script to use the wget executable
included in the Windows Zephyr SDK host tools to download the SDK
components.
