Previously `EventType` contained `SigIndex` as its member based on the
spec, but signature indieces can change after linking, which makes
`EventType` not a constant property of an event. This patch takes
`SigIndex` out of `EventType` and treat it similarly with function
types and makes `SigIndex` a property that any type can optionally
possess.

This is not a spec change; this only affects yaml tests and
binary file results do not change after this patch.
