Title:
  Implement a ResourceThrottle based navigation intercept

Status in Oxide:
  Fix Released

Bug description:
  WebView.navigationRequested currently relies on us turning on an
  option in Chromium to delegate top-level navigations to the browser
  process, which allows applications to intercept them. There are some
  issues with the current approach though:

  - This navigation path is not used in Chromium, and it's not clear how well tested it is.
  - I'm not really sure where it fits in with the re-work of navigations in Chromium (https://docs.google.com/document/d/1cSW8fpJIUnibQKU8TMwLE5VxYZPh4u4LNu_wtkok8UE/edit).
  - It relies on us implementing some of our own navigation logic in oxide::WebView.
  - Navigations that should open in a new tab follow a different code path to window.open() - they go through our navigation logic, and it's impossible to tell whether we should suppress the opener (we never supply the opener to the new webview, which is wrong).
  - This navigation mechanism in Chromium doesn't support POST requests, so the application never has a chance to intercept these.

  We should use the normal navigation paths in Chromium, and instead use
  a ResourceThrottle to intercept navigations. This will introduce a
  small behavioural change in the API - currently,
  WebView.navigationRequested fires before a load starts. With this
  change, a load will start before WebView.navigationRequested fires,
  and it will be followed by a Stopped or Committed load event depending
  on the decision.

  In the future, this will allow us to intercept navigations later -
  just before the load is committed when we have the final URL. However,
  because requests to open a new webview will always have the initial
  URL and they both share the same API (WebView.navigationRequested), I
  don't intend to change this just yet. Instead, I plan to provide a
  replacement set of API's that decouples navigations and window opening
  entirely.
