Modify src/Core/maps/src/Handlers/MapPin/MapPinHandler.Android.cs with contents:
• Add a private field to the `MapPinHandler` class to store a reference to the `Marker` associated with the current `IMapPin`. This could be a Dictionaryto easily track and retrieve the marker for each pin.
• Modify the `MapLocation` method to check if the `Marker` for the given `IMapPin` exists in the dictionary. If it does, update the `Marker`'s position using the `SetPosition` method on the `Marker` instance instead of the `MarkerOptions`.
• Ensure that when a new `Marker` is created (not shown in the provided snippets but likely happening elsewhere in the code when a pin is added to the map), the `Marker` instance is stored in the newly added dictionary.
• Import necessary namespaces for the `Marker` class and any other required classes not already imported.

Description
Changing the Location property on a Microsoft.Maui.Controls.Maps.Pin does not change the location of the Pin on the map.
Steps to Reproduce
pin. Location = something;
Possible Fix
I believe the reason this doesn't work is this line:
https://github.com/dotnet/maui/blob/main/src/Core/maps/src/Handlers/MapPin/MapPinHandler.Android.cs#L14
The handler maintains a MarkerOptions as its PlatformView and loses track of the Marker instance created in the MapHandler. So updating the Pin's Location property updates the MarkerOptions, which has already been used to create the Marker and is therefore no longer useful. The handler should keep track of the created Marker (which is present in a private list on the MapHandler) and update its Position property directly.
