Luca Greco 7b70ba9812 Bug 1688040 - part9: Implement setting/clearing and reporting browser.runtime.lastError from ChromeCompatCallbackHandler::RejectedCallback. r=baku
This patch does:
- add to ExtensionBrowser two new data members to keep track of value for the browser.runtime.lastError and if it was checked while
  the chrome compatible callback was being executed
- add to ExtensionBrowser 3 new methods to set, get and clear the lastError value
- add a reference to the ExtensionBrowser to all API namespaces and API objects classes, because it has to be then propagated to the
  ChromeCompatCallbackHandler instances that are being attached to the promise result of the async API methods calls if the caller did
  pass the optional callback parameter
- tweak the ChromeCompatCallbackHandler class to set the lastError value before calling the callback in ChromeCompatCallbackHAndler::RejectedCallback
  and then clear it after the call has been completed and report it to the console if it wasn't checked
- change the ExtensionRuntime::GetLastError methhod to restrieve and return the value from the ExtensionBrowser instance
