Android - Essentials Geolocation | Added support for MslAltitudeMeters

[bricefriha]

Description of Change

The goal of this change is to add support for MslAltitudeMeters.
We are setting MslAltitudeMeters as the default value for Location.Altitude. If MslAltitude is unavailable or Android version is lower than 34, we just set the regular Altitude.

Fixes #27554

I wonder if we should just add a new property? We could even add 2 new properties an be more explicit:

• EllipsoidalAltitude
• MeanSeaLevelAltitude

Then we obsolete Altitude and keep it returning what it did. Dows Windows have 2 different APIs?

Also saw this:

I agree, but my concern is that we need these for all platforms, which would be a bit redundant for iOS as Altitude is MeanSeaLevelAltitude there.

thanks, that's interesting; we could play around with that perhaps
