There are several places in the WebExtensions framework where we currently
need to repeatedly serialize and deserialize structured clone data as it
passes through message managers, which can lead to significant performance
issues.
This helper class lets us serialize a value directly from the source extension
context into an opaque blob, and then directly deserialize it into the target
context on the other end, with no X-ray overhead or clones into privileged
scopes in-between.

Bill, can you please review the binding changes? Shane, can you please review
the policy service?
This is the first step to making extension policy data directly available to
C++ code without any COM overhead. It tracks the set of currently active
extensions, and how they map to add-on IDs and URIs.

As in part 1, this aims to reduce the overhead of our extension policy logic
by making it directly available to native code with as little JS and XPConnect
overhead as possible.

Change summary:
The existing JavaScript matching code works well overall, but it needs to be
called a lot, particularly from hot code paths. In most cases, the overhead of
the matching code on its own adds up enough to cause a problem. When we have
to call out to JavaScript via XPConnect to make a policy decision, it adds up
even more.
These classes solve both of these problems by a) being very fast, and b) being
accessible directly from C++. They are particularly optimized for the common
cases where only literal or prefix matches are required, and they take special
steps to avoid virtual calls wherever possible, and caching computed URL
values so that they can be reused across many match operations without
additional overhead.

This is presently only relevant for XHRMT, so XHRWorker will just report that
everything's a-ok for now.
As noted inline, the permanence of this measure is to be evaluated in
Firefox 60 in bug 1368540.

- Added new chrome-only webidl methods to be used by browser UI and WebExtensions
- Implemented bitmasked group visibility for VR sessions to enable switching
between chrome and regular content presentations.
- Implemented throttling mechanism to avoid runaway, unthrottled render loops
for VR sessions that are hidden by group visibility bitmasks or due to
lower level platform VR events, such as during the Oculus
"Health and Safety Warning".
- Simplified the PVRManager IPC protocol while extending it to support
VR session groups and later WebVR content performance profiling API's.
- Removed the last WebVR related sync IPC call.
