FrameLoader::shouldAllowNavigation uses Frame for context rather than Document
https://bugs.webkit.org/show_bug.cgi?id=81020

Reviewed by Eric Seidel.

Source/WebCore:

The vast majority of security checks in the browser should use a
ScriptExecutionContext (aka a Document) to designate "who" is
attempting to perform a given action.  Unfortunately,
shouldAllowNavigation was using a Frame to designate "who" is
attempting the navigation.

In cases when the executing script is "inactive" (i.e., belongs to a
document that is not currently displayed in a Frame), using the Frame
can cause us to grant the script the privileges of the document that's
currently displayed in the Frame rather than the one that contains the
script.

This patch moves shouldAllowNavigation from FrameLoader to Document
(and renames it to canNavigate), effectively change the context object
from a Frame to a Document.

    - canNavigate is copied from FrameLoader::shouldAllowNavigation.
      I've added a null-check bailout if the document is inactive.
