This commit adds support for the `static: true` flag in `ViewChild` queries. Prior to this commit, all `ViewChild` queries were resolved after change detection ran. This is a problem for backwards compatibility because View Engine also supported "static" queries which would resolve before change detection. Now if users add a `static: true` option, the query will be resolved in creation mode (before change detection runs). For example: ```ts @ViewChild(TemplateRef, {static: true}) template !: TemplateRef; ``` This feature will come in handy for components that need to create components dynamically.
