+ Web Inspector: re-implement RawSourceCode.
+ https://bugs.webkit.org/show_bug.cgi?id=67609
+
+ RawSourceCode content and source mapping loading logic is too complex, re-implement it using simpler semantics:
+ 1) Initially, RawSourceCode doesn't have any content or mapping because content loading and
+ formatting operations are asynchronous, it only has scripts metadata. We don't update UI right
+ after RawSourceCode creation until full RawSourceCode representation is ready (content + mapping).
+ 2) When RawSourceCode representation is ready (e.g. resource is finished, or content is formatted
+ if in pretty-print mode) we dispatch SourceMappingUpdated event to notify the listeners that
+ source code should be shown to user and raw locations should be converted to ui locations
+ (to show breakpoins, messages, call frames etc in UI). At this moment, all source file's content
+ is ready for loading and source mapping is available.
+ 3) Later, RawSourceCode representation may change again, e.g. if pretty-print mode is toggled, or
+ blocked resource is finished etc., in that case SourceMappingUpdated is dispatched again to update
+ source code, links and decorations in UI.
+
