On Android, a `Picker` is replaced by views without id when opening it #16284

Description

On Android, the Picker control is represented by an EditText view when closed. When opened, it is replaced by a group of views that do not have an id or semantic properties. This makes it really difficult to use with UI tests.

Steps to Reproduce

  1. Create a File > New .NET MAUI App
  2. Add a Picker like so: 
    <Picker Title="My picker"
    SemanticProperties.Description="This is the semantic properties description for the Picker"
    SemanticProperties.Hint="This is the semantic properties hint for the Picker">
<Picker.ItemsSource>
    <x:Array Type="{x:Type x:String}">
        <x:String>A</x:String>
        <x:String>B</x:String>
        <x:String>C</x:String>
    </x:Array>
</Picker.ItemsSource>
</Picker>
  3. Inspect the app using Appium with platformName = Android and appium:automationName = UiAutomator2
  4. Tap the picker so that the options A, B, C show up

Expected outcome: the Picker popup elements (A, B and C) can be found in Appium using a proper method of selection. Actual outcome: the Picker popup is represented by views that are "anonymous" as seen below

Adding the AutomationId does not solve this issue - the elements still remain "anonymous".
