Bug 1966981 [wpt PR 52603] - Expose SnapEvent constructor, 

Automatic update from web-platform-tests
Expose SnapEvent constructor

The constructor for the SnapEvent interface was omitted in the
interface definition in snap_event.idl. This patch corrects this
omission.

The change is put behind a flag as we might need to send out a Blink
PSA.
