I don't think we should do this in this PR, but I'm tempted to ask for an additional set of constants in google.cloud.bigquery.enums that has all the scalar types defined as objects (without name & description). I imagine that will be useful when we eventually create an "array of structs query parameter" code sample.

Sounds reasonable, let's do it in a follow-up PR. 👍
Edit: It's actually very straightforward (if I understood it correctly, that is), thus added that in an extra commit.

Fixes #463.
This PR adds an optional type info parameter to ArrayQueryParameter so that array query parameters with STRUCT items can be used in queries even if they are empty. This is a solution similar to the one used in e.g. the Ruby client.
(for non-struct items the type can always be determined by using the array_type argument)
