[ios] Basic support for CarPlay/phone mode switch

[MontakOleg]

Allow using OrganicMaps on iPhone while connected to CarPlay, see quick demo here – #763 (comment)

This is naive approach with just calling the code that usually get called on CarPlay connect/disconnect events, at first glance it works fine, but help with testing is welcome.

Resolves #763

Strings translation note:
I added new string carplay_continue_on_the_phone with translations from DeepL.

Also I copy-pasted carplay_used_on_the_phone_screen and carplay_continue_in_the_car from Android Auto as is, they don't need translation.

Wow, this is cool. @kirylkaveryn and I discussed that we want to start working on this feature just a few days ago. Thanks for contributing!

[biodranik]

Thanks for your contribution!

@kirylkaveryn @fabwu can you please review and test if it works on your devices?

[fabwu]

This is great! Let me test this on my device and I'll give you feedback.

I've just done a quick test in my car. The switch between CarPlay and the phone works 🥳

I noticed that the zoom level is not correct if you switch back to the phone:

Hmm, we have the same DPI problem as in AA:
#5761
#5760

That's weird. I thought it should work fine with Metal

Thanks a lot for this fix! It really works well except the resolution issue.

Would it be better to make this button more visible?

[MontakOleg]

@fabwu @AndrewShkrob thanks for pointing out about scale issue. updateAppearanceFromWindow() fixes the problem, I updated the code.

Thanks to everyone who participated! Is it ready for test/review/merge?

@biodranik I have a few questions (see threads), but in general did everything planned and waiting for review.

[MontakOleg]

I might found one other bug. If you switch from CarPlay to the phone and disconnect CarPlay (closing the window in the Simulator), the arrow is in the upper left corner and not centered anymore.

@fabwu, thank you for one more report! Should be fixed now.

I tested these changes in my car and the switch works even within a navigation session. I can't help with the layout of the button so I have no more things to add here.

Awesome, this is a critical fix for many users, me included ) Thanks to everyone for implementing, testing and reviewing the PR. It is a great example of team work and the power of the community! I'm sooo happy to see it, and very grateful for your time spent on it ❤️ 🙏 🚀
