Timothy Flynn 5f8d852dae LibWebView+UI: Migrate Ladybird's command line flags to LibWebView 
Currently, if we want to add a new e.g. WebContent command line option,
we have to add it to all of Qt, AppKit, and headless-browser. (Or worse,
we only add it to one of these, and we have feature disparity).

To prevent this, this moves command line flags to WebView::Application.
The flags are assigned to ChromeOptions and WebContentOptions structs.
Each chrome can still add its platform-specific options; for example,
the Qt chrome has a flag to enable Qt networking.

There should be no behavior change here, other than that AppKit will now
support command line flags that were previously only supported by Qt.
