Temporary revert: Introduce include directive to make_private_script_source.py

Reason: As discussed with @haraken over IRC, we need to migrate to using chromium
resource, grd, system. In that we may need to think over how to use the include directive.

One of the harmony modules, [1], describes about using the 'import "module-name"' directive.
We could consider using that as well. As this needs some discussion, we decided to revert
this patch first and reconsider landing this once the formal decision is made about it.

Fix WebCore.Scripts.ParserBlocking.TimeBetweenLoadedAndCompiled

1) The results were skewed by scripts from the same resource being ran several
times (so we saw times > 10 s).

2) Script run time was included in the measurement, and it shouldn't be.

WebCore.Scripts.Deferred.TimeBetweenLoadedAndCompiled is removed for now (to be
fixed later, when it's really needed). Tracking whether a deferred script was
already loaded when requested is more complicated.

IDL: Remove support for [LogPreviousValue] extended attribute

Also remove the logSetter() overload taking an old value parameter from
the WebDOMActivityLogger interface, since there are no calls to it.
