- Updated url::Origin version of CanAccessDataForOrigin() to verify
  precursor information if present and preserves existing behavior
  for opaque origins w/o precursor info. (i.e. only allow if lock is
  not set).
- Created tests for url::Origin version of CanAccessDataForOrigin().
- Added a few new tests cases for GURL version of
  CanAccessDataForOrigin().
