[feat] [v2] add files to windows installer config

[pronebird]

Describe the problem

Unlike macOS target, Windows target (in tauri.conf.json) does not have files to bundle more stuff with the app. It would be great to add that configuration setting too, just like for all other platforms. When using custom NSI file I have to provide all the same, but I'd really love to leverage Tauri's template.

Describe the solution you'd like

I'd like to specify files the same way I do for other platforms, like macOS.
