Web Inspector: streamline Console's MessageType and MessageSource semantics.

Web Inspector: streamline Console's MessageType and MessageSource semantics.
https://bugs.webkit.org/show_bug.cgi?id=68342

Source/WebCore:

This change fixes semantics of the MessageSource and MessageType:
MessageSource is now the source of the message (be it Network, HTML
parser or Console API). MessageType is only defined for the Console API
messages and contains the name of the API call (log, dir, dirxml, etc.).
Subsequent https://bugs.webkit.org/show_bug.cgi?id=66371 will make MessageType
private to the inspector.
