[CR] feat: iOS build

[sonphantrung]

Summary

None

Purpose of change

1. I want to play DDA on my iPhone
2. The ones provided on the App Store are outdated and I can't afford as I'm broke
3. I want to have an easier way of compiling iOS builds

Describe the solution

This is a sequel of @smileynet's #61550 (attribution will be added later). Additionally:

• I have fixed some "angled" includes
• I aimed for feature parity with Android. To achieve this, I utilized Swift's fairly new C++ interop feature for exposing vars to existing code

Describe alternatives you've considered

Play on PC 😢

Testing

Additional context

Compared to compiling Mindustry/Shattered Pixel Dungeon, this thing is far tougher for a person not having a Mac like me. Any helps are appreciated!

Compiled (albeit having problems)

OK, so now I'm having this problem when compiling:

How is this error supposed to happen?????? It's defined in input_context.h w/ correctly added ifdefs!

In your build, will it have support for ipads with keyboards? Thanks!

TBF, it should, as SDL have done most of the heavy-lifting already, but I don't know whether the key repeat bug still exists nowadays.

Cool. That's good to know. Also, on Yuri Apollov's app, every time you press Enter or ESC, it has a chance to fire twice and it's really irritating, making the game nearly unplayable. This started when I updated to iPadOS 17 and I've seen no bug reports on the internet.

I am adding the "Help Wanted" tag as you asked for help in #77476

Now I see the problem isn't defined. I cannot help myself, I don't even own any Apples. But I recommend asking on Discord.

Current problems:

• Compiler complains about certain classes/variables from input_context.h isn't available (which is why I temporarily removed the ifdef guards)
• The (screen) rectangle doesn't fully respect the phone's screen (leading to the game UI only appears on the top-left corner)
• Shortcuts don't spawn right away (had to do the hacky "putting app to background, trigger on-screen keyboard input" for it to show up, barely.
• Touch input doesn't work/functioning correctly (Putting in debug msgs does show up btw, but things like the joystick, main menu select, shortcut inputs don't work)

And I'm banned from the Dev Discord server, so I can't do much other than researching stuffs myself.

• Rebase if these are relevant Fix mac tests running as raw binary. #78265, Fix mac CI #77818.
