Nika Layzell 349de0b692 Bug 1616353 - Part 7.7: Remove window initialization properties which are redundant with nsOpenWindowInfo, r=kmag
These properties used to be passed to newly created content windows in many
different ways, but are now unified under nsOpenWindowInfo. This patch cleans up
the remaining properties.

* Calls the given function as soon as a style or layout flush for the

* resolves to the callback's return value after it executes.
*
* In the event that the window goes away before a flush can occur, the
* callback will still be called and the Promise resolved as the window
* tears itself down.
*
* The callback _must not modify the DOM for any window in any way_. If it
* does, after finishing executing, the Promise returned by
* promiseDocumentFlushed will reject with
* NS_ERROR_DOM_NO_MODIFICATION_ALLOWED_ERR.
*
* Note that the callback can be called either synchronously or asynchronously
* depending on whether or not flushes are pending:
*
* The callback will be called synchronously when calling
* promiseDocumentFlushed when NO flushes are already pending. This is
* to ensure that no script has a chance to dirty the DOM before the callback
* is called.
*
* The callback will be called asynchronously if a flush is pending.
*
* The expected execution order is that all pending callbacks will
* be fired first (and in the order that they were queued) and then the
* Promise resolution handlers will all be invoked later on during the
* next microtask checkpoint.
*
* Using window.top.promiseDocumentFlushed in combination with a callback
* that is querying items in a window that might be swapped out via
* nsFrameLoader::SwapWithOtherLoader is highly discouraged. For example:
*
* let result = await window.top.promiseDocumentFlushed(() => {
* return window.document.body.getBoundingClientRect();
* });
*
* If "window" might get swapped out via nsFrameLoader::SwapWithOtherLoader
* at any time, then the callback might get called when the new host window
* will still incur layout flushes, since it's only the original host window
* that's being monitored via window.top.promiseDocumentFlushed.
*
* See bug 1519407 for further details.
*
* promiseDocumentFlushed does not support re-entrancy - so calling it from
* within a promiseDocumentFlushed callback will result in the inner call
* throwing an NS_ERROR_FAILURE exception, and the outer Promise rejecting
* with that exception.
*
* The callback function *must not make any changes which would require
* a style or layout flush*.
*
* Also throws NS_ERROR_FAILURE if the window is not in a state where flushes
* can be waited for (for example, the PresShell has not yet been created).
*
* @param {function} callback
