Add Essentials Maps TryOpen

[jfversluis]

Description of Change

Port from this Xamarin.Essentials PR here: xamarin/Essentials#1665

Note, this feature will not be merged in Essentials, but it was approved at the time, so I thought it might be a nice addition for .NET MAUI

• Added Map.TryOpenAsync method for every Map.OpenAsync.
• I also did some refactoring of this module to remove code duplication.
• I contemplated that I could also add Map.CanOpenAsync. However, I'm not sure how to implement this on iOS.
• I came across weird behavior on Android 11. I could run geo intent, however PackageManager.QueryIntentActivities() always returned me empty list for some reason. I did some research, and I think that it's necessary to add this intent to AndroidManifest, like all other intents.
  <intent> <action android:name="android.intent.action.VIEW" /> <data android:scheme="geo" /> </intent>
• I'm not sure whether I should write some tests for this.

API Changes

Added:

• Task<bool> TryOpenAsync(Location location)
• Task<bool> TryOpenAsync(Location location, MapLaunchOptions options)
• Task<bool> TryOpenAsync(double latitude, double longitude)
• Task<bool> TryOpenAsync(double latitude, double longitude, MapLaunchOptions options)
• Task<bool> TryOpenAsync(Placemark placemark)
• Task<bool> TryOpenAsync(Placemark placemark, MapLaunchOptions options)

@mattleibow is there a specific reason that not all overloads are surfaced in the IMap??

Do we want to have XML API docs for this? Do we generate that? How does it work?

Mostly because a lot are the same api, just different parameters. The overload are echoed via extension methods in the shared code.

Not yet for the interfaces. We need to. And the extension methods

does this only check if some map is installed to be opened or should it open maps too?
