feat: Add default download handler

[FabianLars]

I wonder if the is_local check is a bit too much? after all browsers download files from all websites as well 🤔

I forgot to add a note about this on the builder methods. Will do that tomorrow (Friday)

Should we enable this in wry by default instead? I feel like it doesn't quite make sense to block downloads by default anyways, and it is already the case for webview2

Don't feel like we need to restrict that either

Ah now that you mention it i meant to disable it by default on windows but forgot about it. Anyway, i don't care about the default so if you prefer that i'll change it in Wry.
