Tdesktop: Allow using of different map providers

[Wohlstand]

The issue would be similar to #2787, however, it's for general ability to use any other map provider but Google Maps.

There are examples of why it needs to support other map providers:

• Taste of users: Personally I prefer Yandex Maps for visually better drawing and colors choice
• Details of regions: For example, Yandex Maps has much more details of Russian area (Google Maps is often missing up villages and far places while Yandex showing them up in all details)
• Availability in certain regions: The Google is banned in China, therefore, it's required to use any other map provider but Google Maps to let Chinese people see a map without proxies and VPNs.

You can make some sort of config that will allow a user to manually construct the URL template of the map provider with giving of position coordinates in a certain formats, etc. (for desktop) if you don't want care about every individual map provider yourself. And using any available mobile map application by user's choice (you may notice user if some features wouldn't work in other map provider app).

Just a comment (might be offtopic): on Windows 10, clicking on Geo message opens UWP application "Maps". However, on Windows 10 LTSC, which has no Metro apps, clicking on such message opens Windows's native popup, asking to open Microsoft Store (which is also absent from LTSC).

@MasterGroosha, yeah, I can see the same on Windows 8.1 after manual removing of "Maps" UWP application: It will pop-up the same message as you see. I did that at my mother's computer where she didn't like ugly Bing maps thing, and I helped her to get rid of "Maps". It's only after some time after the restart, it will finally open Google Maps in the browser by URL.

@Wohlstand Unfortunately, it doesn't open browser for me :(

So, several suggestions:
1) Add "Copy location" option to Geomessage context menu.
2) Allow to choose maps provider (Yandex, Google, Bing, OpenStreetMaps).

Option "1" is easier of course.

The links from location messages go to Google Maps, but the tiles actually use OpenStreetMap. You can see that, if you know differences in OSM and GMaps or others or even (accidental) trap streets. That is why Telegram needs to attribute OpenStreetMap (see #6830 for that).
Am I correct in assuming that this issue is about the links and not the in-app tiles?

I think this is still an issue
