Summary
Remove the SVGZoomEvent interface and the corresponding onzoom attribute.
Motivation
SVGZoomEvent doesn't work at all in Blink. It can be created and hooked up using onzoom="..." but it is never fired by the browser.
It has been removed from the SVG 2.0 specification:

https://github.com/w3c/svgwg/commit/3844475c05b865e961a0bc52cd63e627412360e2
Compatibility Risk
A httparchive search has been conducted:
https://code.google.com/p/chromium/issues/detail?id=367890#c11
indicating very low usage. From the search it looks likely that the event is possible to remove.
The interface has been around in WebKit and Blink for a long time. Originates in:

Requesting approval to remove too?
Yes, M52 is the suggested milestone.
