Introduces post format support for both the Query Block with the new parameter `format`. In the `build_query_vars_from_query_block()` function, this is converted to a `post_format` taxonomy query passed to `WP_Query`.

Also introduces the `format` parameter to the REST API's Posts controller to support the feature in the Query block. The parameter type is an enumerated  string accepted the post formats supported by each post type.
