Web Inspector: refactor text viewer decorations code.

We have several kinds of TextViewer decorations - diffs, messages, breakpoints, execution line. During TextViewer initialization, live edit, and SourceFrame recreation, each kind is processed separately. Also, methods for updating decorations bloat SourceFrame interface (addMessage, setExecutionLine, ...).
Instead, we may introduce several TextViewerDecoration implementations and handle them uniformly in most cases.
