Set DatePicker Style

[acaliaro]

Description

Currently it is possible to set some properties of the DatePicker, but only for the object displayed on the UI. In Android it seems that it is not possible to set, via "Style", the properties of the popup that appears when the DatePicker control is pressed. For example, it seems that to change the popup title color, you need to work on the Android styles (which seems to create problems as it also changes the style of the splashscreen: https://learn.microsoft.com/en-us/answers/questions/1047070/change-title-and-selected-date-colors-in-android-d). It would also be useful to change the settings of the dialog via netmaui handlers

                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="Normal" />
                    <VisualState x:Name="Disabled">
                        <VisualState.Setters>
                            <Setter Property="TextColor" Value="{AppThemeBinding Light={StaticResource Gray200}, Dark={StaticResource Gray500}}" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateGroupList>
        </Setter>
    </Style>

Intended Use-Case

The request is motivated by being able to manage the styles of the dialog that appears when the DatePicker control is pressed without having to touch the Android styles. I think this could also be useful for the TimePicker and the various Dialogs in general
