Would it be possible to make DOMWindowProperty a GC-mixin before landing this
change? (Then we can make this CL smaller.)

The only potentially tricky part I can think of right now is how to get the
frame clearing to be reliably done; I can investigate.

The DOMWindowProperty changes to make it a GC mixin was handled via r181717 (
https://codereview.chromium.org/552733003/ ) & this CL has been rebased on top
of it.

Reduced the file footprint by ~50 :)
