This commit implements the following changes to get registration.https.html working.
1) Fail with NS_ERROR_DOM_SECURITY_ERR where the spec requires it.
2) Propagate JSExnType to ServiceWorkerManager::HandleError() so that a JS
exception object with the correct .name can be created.
3) Fail with security error on redirect failure.
4) Check fetched script's mimetype.
5) Add missing python server files for web-platform-tests.
6) Update web-platform-tests expected data.
7) Several tests have been changed to use TypeError or more appropriate JS
errors based on my reading of the spec.

waitUntil() has been updated to accept multiple calls and concatenate them into Promise.all().
activation does not fail any more even if the promise(s) passed to waitUntil() reject.

The second test, which checks for NetworkError is incorrect.
[[Update]] step 12 states:
"If response is a network error or response's status is not in the range 200 to 299, then:
1. Reject p with a TypeError."
which specifically converts the NetworkError (due to 404) to a TypeError.

Right now, synthetic Responses did not have a valid channel info. When these
were saved in the Cache, and then restored, the restored Response did have
a ChannelInfo, but that ChannelInfo did not have a valid security info.
Passing this to respondWith() then caused the interception to fail.
This patch modifies Response::Constructor() to initialize its ChannelInfo from
the global. ChannelInfo can now initialize itself from a nsIDocument. All
workers now store their ChannelInfo on the WorkerLoadInfo.

This is motivated by three separate but related problems:
1. Our concept of recursion depth is broken for things that run from AfterProcessNextEvent observers (e.g. Promises). We decrement the recursionDepth counter before firing observers, so a Promise callback running at the lowest event loop depth has a recursion depth of 0 (whereas a regular nsIRunnable would be 1). This is a problem because it's impossible to distinguish a Promise running after a sync XHR's onreadystatechange handler from a top-level event (since the former runs with depth 2 - 1 = 1, and the latter runs with just 1).
2. The nsIThreadObserver mechanism that is used by a lot of code to run "after" the current event is a poor fit for anything that runs script. First, the order the observers fire in is the order they were added, not anything fixed by spec. Additionally, running script can cause the event loop to spin, which is a big source of pain here (bholley has some nasty bug caused by this).
3. We run Promises from different points in the code for workers and main thread. The latter runs from XPConnect's nsIThreadObserver callbacks, while the former runs from a hardcoded call to run Promises in the worker event loop. What workers do is particularly problematic because it means we can't get the right recursion depth no matter what we do to nsThread.
The solve this, this patch does the following:
1. Consolidate some handling of microtasks and all handling of stable state from appshell and WorkerPrivate into CycleCollectedJSRuntime.
2. Make the recursionDepth counter only available to CycleCollectedJSRuntime (and its consumers) and remove it from the nsIThreadInternal and nsIThreadObserver APIs.
3. Adjust the recursionDepth counter so that microtasks run with the recursionDepth of the task they are associated with.
4. Introduce the concept of metastable state to replace appshell's RunBeforeNextEvent. Metastable state is reached after every microtask or task is completed. This provides the semantics that bent and I want for IndexedDB, where transactions autocommit at the end of a microtask and do not "spill" from one microtask into a subsequent microtask. This differs from appshell's RunBeforeNextEvent in two ways:
a) It fires between microtasks, which was the motivation for starting this.
b) It no longer ensures that we're at the same event loop depth in the native event queue. bent decided we don't care about this.
5. Reorder stable state to happen after microtasks such as Promises, per HTML. Right now we call the regular thread observers, including appshell, before the main thread observer (XPConnect), so stable state tasks happen before microtasks.
