Add permission automation support for registerProtocolHandler

After we landed in rXXXX the new protocol-handler permission descriptor we can now use it to set the permission status in WPT, using WebDriver.

This CL changes the registerProtocolHandler method implementation of both the content-shell and Chrome to check whether a permission status has been already set. In content-shell we don't ask the user, but in chrome we use the RequestPermissionManager, which eventually may launch a prompt dialog.

We only have manual tests for the registerProtocolHandler method, precisely due to the user_gesture requirement and the prompt dialog. We
can now use the Permission interface, via the extension commands [1] that are implemented by the WebDriver API.

In the case of the content-shell, we are just looking for any permission status already set and in the WebTestPermissionManager instance. For Chrome, instead, we have added a new method to check the devtools_permission_overrides_ cache. We want in this case to avoid getting the actual permission status (using the helper).

There is an ongoing discussion [2] with the WPT community in the issue in this CL.
