RecentsView: Unconditionally hide split option for Go-enabled targets

Split option should be disabled for Go-enabled targets as seen
in go/quickstep/res/layout/overview_actions_container.xml.
Here's the snippet:

        <!-- Unused. Included only for compatibility with parent class. -->
        <Button
            android:id="@+id/action_split"
            style="@style/GoOverviewActionButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableStart="@drawable/ic_split_vertical"
            android:text="@string/action_split"
            android:theme="@style/ThemeControlHighlightWorkspaceColor"
            android:visibility="gone" />

        <Space
            android:id="@+id/action_split_space"
            android:layout_width="0dp"
            android:layout_height="1dp"
            android:layout_weight="1"
            android:visibility="gone" />
