Web Inspector: Improve names in Debugger Call Stack section when paused
https://bugs.webkit.org/show_bug.cgi?id=152398

Reviewed by Brian Burg.

Source/JavaScriptCore:

* debugger/DebuggerCallFrame.cpp:
(JSC::DebuggerCallFrame::functionName):
Provide a better name from the underlying CallFrame.

* inspector/InjectedScriptSource.js:
(InjectedScript.CallFrameProxy):
Just call functionName, it will provide a better
than nothing function name.

* runtime/JSFunction.cpp:
(JSC::getCalculatedDisplayName):
Use emptyString().

* interpreter/CallFrame.h:
* interpreter/CallFrame.cpp:
(JSC::CallFrame::friendlyFunctionName):
This is the third similiar implementation of this,
but all other cases use other "StackFrame" objects.
Use the expected names for program code.

Source/WebInspectorUI:

* UserInterface/Controllers/DebuggerManager.js:
(WebInspector.DebuggerManager.prototype.debuggerDidPause):
Use a new fromPayload helper to construct the CallFrame and share code.

* UserInterface/Models/CallFrame.js:
(WebInspector.CallFrame.functionNameFromPayload):
(WebInspector.CallFrame.programCodeFromPayload):
(WebInspector.CallFrame.fromDebuggerPayload):
(WebInspector.CallFrame.fromPayload):
Add a new way to construct a call frame. There are two kinds of
CallFrame payloads in the protocol:
- Debugger.CallFrame, this new path
- Console.CallFrame, the pre-existing path
