Original change's description:
> [pdf] Change IsPdfExtensionUrl() to IsPdfExtensionOrigin()
>
> The check really pertains to the origin, not the entire URL. It also
> allows for a merging of logic between IsPdfExtensionOrigin() and
> IsPdfInternalPluginAllowedOrigin(). Furthermore, it makes the function
> more appropriate for security checks.
>
> Use IsPdfInternalPluginAllowedOrigin() in the implementation of
> ChromePrintRenderFrameHelperDelegate::GetPdfElement().
>
