Web Inspector: Use console.timeStamp instead of console.markTimeline
https://bugs.webkit.org/show_bug.cgi?id=117810

Source/WebCore:

Webkit supports both console.timeStamp and console.markTimeline.
And they do the exact same thing.
This patch gets rid of console.markTimeline for Chrome/Firebug compatibility.

No new functionality, no new tests.

* WebCore.order:
* page/Console.cpp:
* page/Console.h:
* page/Console.idl:

LayoutTests:

Use 'console.timeStamp' instead of 'console.markTimeline' in LayoutTests.
And remove inspector/timeline/timeline-mark-timeline.html.

* inspector/timeline/timeline-mark-timeline-expected.txt: Removed.
