Add deep link support for google maps within iOS comgooglemapsurl://

[brh55]

Open to anyone to tackle, but this would avoid the double opening of browser to native maps. Use the comgooglemapsurl:// so that the existing parameters should work.

1. Use Linking.canOpenURL() to verify device has google maps
2. Proceed to set url to comgooglemapsurl://

Test to make sure nothing is broken, and submit some test to validate this logic.
