SemanticsTag class Null safety

A tag for a SemanticsNode.

Tags can be interpreted by the parent of a SemanticsNode and depending on the presence of a tag the parent can for example decide how to add the tagged node as a child. Tags are not sent to the engine.

As an example, the RenderSemanticsGestureHandler uses tags to determine if a child node should be excluded from the scrollable area for semantic purposes.

The provided name is only used for debugging. Two tags created with the same name and the new operator are not considered identical. However, two tags created with the same name and the const operator are always identical.
