Introduce chrome.shell.createWindow stub API for app_shell

The chrome.app.window.create API has too many Chrome dependencies to be practically extracted from src/chrome. Rather than create an incomplete chrome.app.window API stub just for app_shell, introduce chrome.shell.createWindow which can be used in place of chrome.app.window with a small stub.

* Introduce chrome.shell.createWindow for app_shell.
* Introduce an app_shell_resources target to hold the resource for the chrome.shell custom bindings JS.
* Extend ExtensionsRendererClient to allow an extensions embedder to supply additional custom APIs.
* Modify the Calculator example to use a small chrome.shell polyfill for window creation.

BUG=349042
TEST=browser_tests *Extension*, app_shell --app=<path/to/calculator/app> loads calculator
TBR=isherman@chromium.org for mechanical update of existing ExtensionFunction enum in histograms.xml
