This is similar to Services.tm.idleDispatchToMainThread, but provides an
IdleDeadline argument to its callbacks, the same way that
Window.requestIdleCallback does.
The IdleDeadline argument was necessary for my first attempt at this bug. It's
not necessary for the current version, but I suspect it will be useful in
other areas, and it also avoids some XPConnect overhead, so it's probably
worth keeping.

This will allow us to verify the entire detection pipeline in real nightly
builds, which will give us confidence that real heap corruption will be
detected and reported properly.

As part of the normalization process for WebExtension API calls, we need to
extract and validate the full set of value properties (including properties
X-rays would normally deny access to) from cross-compartment objects. This
currently involves waiving X-rays, enumerating property descriptors, and
unwaiving X-rays - all through X-ray wrappers and waivers - and generating a
lot of expensive and short-lived wrappers in-between.
This helper reads out the list of safe properties from within the object's
compartment, and then copies them over to an object in the target compartment,
without any X-ray overhead, or any unnecessary intermediate wrappers or
compartment switches. It cuts about 40% off the overhead of our normalization
code.

In the code that I'm profiling, the XPC WrappedNative overhead of calling
these functions adds up to about a quarter of the time spent executing the
code. The overhead of the WebIDL versions is negligible.

Add an origin attribute called 'firstPartyDomain'.
This value will be extracted from the URL bar.
And the purpose of this attribute is used to isolate the data-jars.
Please see the tor documentation.

The idea is like a superset of 'reject third party cookies', but not
only apply for cookies, it also applies to all data-jars like localStorage,
indexedDB and so on.
So basically an iframe will have its own data-jar, and this data-jar is
isolated by the URL from URL bar, for instance, an iframe
https://facebook.com inside https://cnn.com won't share data-jar with
the iframe (https://facebook.com) in https://bbc.com

This change renames OriginAttributes.mInBrowser to mInIsolatedMozBrowser and
nsIPrincipal::GetIsInBrowserElement to GetIsInIsolatedMozBrowserElement. Other
methods that pass these values around also have name changes.
Tokens such as "inBrowser" have previously been serialized into cache keys, used
as DB column names, stored in app registries, etc. No changes are made to any
serialization formats. Only runtime method and variable names are updated.
No behavior changes are made in this patch, so some renamed methods may have
nonsensical implementations. These are corrected in subsequent patches
focused on behavior.
