Chris Bracken c9085a9074 null-annotate SemanticsUpdateBuilder.updateNode (flutter/engine#18552) ...

The underlying _updateNode call requires that all parameters be set
non-null. There's a single call site in the framework in
lib/src/semantics/semantics.dart in SemanticsNode.updateWith(). At that
call site, all parameters are either asserted non-null in the
constructor of SemanticsData or defaulted to null, with the sole
exception of textDirection.

The ergonomics of this method are currently pretty ugly and we should
consider migrating most of the defaulting and assertions that we apply
at the call site up to the definition in dart:ui. That work is filed as
https://github.com/flutter/flutter/issues/57720.
