Pass AtomicStrings as 2 first arguments to V8LazyEventListener::create()

Pass AtomicStrings as 2 first arguments to V8LazyEventListener::create() in
ScriptEventListener as this is what this factory method expects. This avoids
uselessly constructing Strings and then converting them to AtomicStrings.

V8StringResource's v8StringToWebCoreString() should return a StringType

V8StringResource's v8StringToWebCoreString() should return a StringType,
not a String. This avoids useless conversions from String to AtomicString
when StringType is an AtomicString.
