[iOS] Pressing next into a ListView or TableView goes to last element

[tj-devel709]

Description

The code from this PR allows the user to click the "Next" button on the iOS Keyboard (or "enter" on physical keyboard using MacCatalyst) to automatically focus the next UITextField or UITextView (Editor and Entry in Maui).

However, when you press the "Next" button to go into a ListView or TableView, you get sent to the last entry as you can see in the video below:

TableView.mov

It appears that the logical tree reverses the order of the elements in the ListView and TableView and because the Next Navigation uses the logical ordering. Running a slightly different project below, you can see that when we run the maui project on VSMac on MacCatalyst and then attach a debugger inside Xcode and inspect the hierarchy tree, the TableView's entries are backwards.

Steps to see the process in Xcode

1. Open Xcode
2. Run the Maui project on MacCatalyst inside VSMac
3. On Xcode, click the Debug->Attach to Process->{find the maui process and click} dropdown on the top mac toolbar
4. Press the Debug Spray can icon on the left-side panel
   
5. Press the Debug View Hierarchy button (three stacked panels icon) on the bottom bar
6. Observe the view hierarchy on the left panel

From searching inside the ListViewRenderer (when observing similar behavior in the ListView), it seems that elements are in the correct order inside the DataSource so it appears that somewhere else, things are getting reversed.

Steps to Reproduce

1. May need to be inside the Maui repo main branch depending on this PR: [iOS] Better Find Next Textfield Algo #13174 (should work to reproduce this inside Maui main branch in the Sandbox)
2. Add the below xaml
3. Deploy to an iOS device or use the iOS simulator
4. Click the first entry that has the text "Initial Entry"
5. Press the "Next" button on the iOS software keyboard
6. Observe that you go into the last textfield of the tableview "E3" instead of the expected "E1"
7. Notice similar behavior inside a ListView as well. (CollectionView works as expected though)

<VerticalStackLayout
            Spacing="25"
            Padding="30,0"
            VerticalOptions="Center">

            <Entry Text="Initial Entry" ReturnType="Next" />

            <Label Text="TableView" VerticalOptions="End"/>

            <TableView>
                <TableRoot>
                    <TableSection>
                        <EntryCell Label="EntryCell1" Text="E1"/>
                        <EntryCell Label="EntryCell2" Text="E2"/>
                        <EntryCell Label="EntryCell3" Text="E3"/>
                    </TableSection>
                </TableRoot>
            </TableView>
</VerticalStackLayout>
