Alex Rickabaugh 84dd2679a9 fix(core): require 'static' flag on queries in typings (#30639)
This commit makes the static flag on @ViewChild and @ContentChild required.

BREAKING CHANGE:

In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.

@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.
