[renderblocking] Implement render-blocking on script elements

This patch makes RenderBlockingResourceManager to accept scripts as
render-blocking resources, and implements the following parts of the
spec:

  1. Right before fetching a render-blocking script, add it to
    RenderBlockingResourceManager:

https://html.spec.whatwg.org/multipage/scripting.html#script-processing-model:block-rendering

  1. When executing a script, remove it from RenderBlockingResourceManager

https://html.spec.whatwg.org/multipage/scripting.html#script-processing-model:unblock-rendering

  1. When a render-blocking script is removed, also remove it from
    RenderBlockingResourceManager, so that rendering is unblocked even
    without executing the script:

https://html.spec.whatwg.org/multipage/urls-and-fetching.html#blocking-attributes:unblock-rendering
