Remove api.SnapEvent.SnapEvent from BCD

[queengooborg]

This PR removes the SnapEvent member of the SnapEvent API from BCD. The collector reports that the constructor is an illegal constructor in Chromium.

I reported the issue: https://issues.chromium.org/issues/415848477

Instead of removing the data, we could set partial_implementation: true with notes pointing to the issue

[queengooborg]

In Chrome, "Illegal constructor" means that a constructor has not been implemented and exposed, which means that it's not supported. Using partial implementation for a feature that does not have support doesn't seem like the right call.

We can always keep the MDN page around, however, and then reattach the BCD table once the feature is supported?

Using partial implementation for a feature that does not have support doesn't seem like the right call.

The alternative is to set version_added: false, but with the impl_url. That should be fine, no?

I would assume that it's either a bug in the spec or in Chrome.
