fix(javascript): stop reading media preload attributes as Electron preloads

HTML audio and video elements have their own `preload` attribute ("none",
"metadata", "auto"). A React renderer compiles `<audio preload="metadata">`
to `jsx("audio", { preload: "metadata" })`, and the `property:preload`
heuristic reported it as an Electron preload script named `metadata`.

Skip `preload` properties in the props object of a call whose first
argument is the static tag `audio` or `video`. The callee is not checked,
because minified element factories have arbitrary names.
