[print] Add plugin for (silent) print API

Upstream issue: https://github.com/tauri-apps/tauri/issues/4917 / https://github.com/tauri-apps/wry/issues/707

Short term goals:
- All APIs should be available in Rust and JavaScript
- [ ] Windows support
- [ ] macOS support
- [ ] Linux support
- [ ] Print currently displayed page to a PDF file
- [ ] Print currently displayed page with the default printer
- [ ] Make printer configurable - splitting this up because the Windows APIs look a bit tricky

Mid and long term goals are optional in the sense that i don't know if all them are possible to implement.

Mid term goals:
- [ ] Print the current viewport
- [ ] Print an arbitrary area
The webviews have screenshot apis that can take screenshots of the viewport and areas, in case the print apis don't support this.

Long term goals:
- [ ] Android support
- [ ] iOS support
- [ ] Print files that are not part of the frontend but can be opened by the webview
- [ ] Print arbitrary files, i'm not sure how viable this is, it also won't use the webview apis
- [ ] ESC/POS printing (thermal printers). This should probably be a different plugin but i think there will be some overlap so we'll see.

Since https://github.com/tauri-apps/wry/issues/707 is a thing we may end up upstreaming a few APIs but we'll see...

P.S. I don't want to see PRs being open for months/years so we should aim for small scoped PRs even if that means splitting it up per OS.
