Histogram fix: WebCore.Scripts.ParsingBlocking.TimeBetweenLoadedAndCompiled; exclude internal resources.

Some chrome:// scripts are compiled several times after loading; exclude them
from the data. Internal scripts (or scripts loaded via file://) are not interesting
from this histogram's point of view anyway and unnecessarily skew the data.

DevTools: Always show empty placeholder in ObjectPropertySection.

The placeholders are: "No Properties", "No Entries", "No Scopes", etc.
Right now we don't always show it, e.g. console.dir({ foo: { __proto__: null } })

Drive-by: pretty padding in tests with console.dir() and console.trace().
