Subject: [PATCH] Add missing values to semantics action enums (#8033)

This brings the Dart and C++ semantics flag enums back in sync.

In #5902, the ability to move the cursor forward and backward one word
were added to dart:ui, and to the Android embedder, but not to the
SemanticsAction enum on the C++ side.
