Removed some unused functions from the debugger interface

Reviewed by Joseph Pecoraro.

We plan to use the "evaluate" API and debugger activation property access for all the features we need.

Source/WebCore:

* inspector/JavaScriptCallFrame.idl: These are the interfaces I removed.

* bindings/js/JSJavaScriptCallFrameCustom.cpp:
* inspector/InjectedScript.cpp:
* inspector/InjectedScript.h:
* inspector/InjectedScriptSource.js:
* inspector/Inspector.json:
* inspector/InspectorDebuggerAgent.cpp:
(WebCore::InspectorDebuggerAgent::setScriptSource):
* inspector/InspectorDebuggerAgent.h:
* inspector/JavaScriptCallFrame.idl:
* inspector/front-end/RemoteObject.js:
(WebInspector.RemoteObject.prototype.):
(WebInspector.RemoteObject.prototype.setPropertyValue): These files are mechanical removals of code that used
or implemented the interfaces I removed.

Source/WebInspectorUI:

* UserInterface/InspectorBackendCommands.js: Updated by script.

LayoutTests:

* inspector/debugger/debugger-change-variable-expected.txt: Removed.
* inspector/debugger/debugger-change-variable.html: Removed. This test was failing
because we don't support this API.

* platform/mac/inspector/console/command-line-api-expected.txt: This test changed line numbers
because I changed inspector .js files.
