[feat] PDF generation programmatically

[thewh1teagle]

Describe the problem

Current web APIs doesn't have simple way to generate pdf from the current webpage.
3rd party libraries doesn't work well - font issues, or some doesn't preserve text selection.
The webview's built in html -> pdf render works best but requires user interaction after 'window.print`

Describe the solution you'd like

It will be useful to be able to convert the current page (html to pdf) programmatically by leveraging webview's APIs in wry
Since there's no option in js to save the page as pdf
