Fix ridiculous DOM proxy getter performance
This implements the missing shadowing checks that were causing us to take many slow paths when dealing with proxy objects. Verified by running `tests/html/binding_perf.html` before and after and observing a 12x improvement.

Support pair and value iterable WebIDL bindings
The actual iterator implementation and JSAPI calls related to setting up the interface are ported directly from Gecko's Codegen.py, IterableIterator.h, and IterableIterator.webidl. The changes to support multiple interfaces in one file are required because the internal iterator interface the parser generates gets associated with the original interface's WebIDL file. It seemed like a good time to address #571 in that case.

<!-- Reviewable:end -->
Each interface gets its own module named ${Interface}Binding. Structs, enums, and callbacks
continue to use the root module of the binding file. If there is only one interface in the
file, we generate reexports for several public APIs and types so that existing DOM implementations
don't need any modifications. When multiple interfaces exist, the reexported names get the interface
name prepended (eg. FooWrap instead of Wrap).
As part of this work, stop glob-importing all DOM types in every generated binding and start generating
more targeted lists of relevant types based on the methods, members, etc. of WebIDL types that are in use.
