[3.x] [tvOS] Basic tvOS Support

[naithar]

Added basic tvOS support.
Implements already closed but not implemented proposal: godotengine/godot-proposals#224

Platform code is based on iOS platform code with minor changes (some iOS stuff isn't available on tvOS).
Audio interruption was also removed - AppleTV don't seem post interruption notification correctly or in right order, which results in game freezing after application loses focus.
Keyboard input backed was changed so keyboard input actually works.
Input is handled by controllers. Apple/Siri Remote are also considered controller (micro)

Export code (including plugins) is also based on iOS platform since both of them export into Xcode project.
But export is also simpler:

• Launch screen is storyboard based (no need for launch images)
• tvOS project supports empty Apple Team ID
• Icons, Signatures and certificates are handled by Xcode project

Core code has been modified to address tvOS unsupported features - no fork and execvp.
Rendering code has been modified for tvOS to use same paths/methods as iOS's.

Mono haven't been ported.
GDNative uses same configuration as iOS platform.

• Exports correctly
• Runs correctly
• Handles input
• Plugins support (example https://github.com/naithar/godot-ios-plugins/tree/feature/tvos-support)
• GDNative support (tvOS support godot-headers#85 Support tvOS compilation godot-cpp#512)
• App Store upload

Build container and script PRs: godotengine/build-containers#71, godotengine/godot-build-scripts#21

Since linux-compiled binaries are required to use use_lto to pass App Store checks, I'll place macOS built tvOS templates and binaries here: unofficial tvOS templates

⚠️ I only reviewed the gdnative part of this PR (and it seems pretty fine for me 😄 )

[naithar]

Reverting this PR (as well as one for master branch) back to draft for now.
I'm working on simplifying code sharing between UIKit based platforms - iOS and tvOS. Progress is here: naithar@4c30d17

It's working, but I'm not happy with the overall code structure/cleanliness for now.

Hi,

Any news when it will be available?

Good day! There was a need for tvOS
Is it enough just to merge into the 3.4 branch?

This won't be merged in 3.4.x as patch releases are now dedicated to bug fixes only. This can be merged for 3.5 if this is rebased against the latest 3.x branch and tested again.

@naithar Can you rebase?

It was a question to the author of a branch.
I was unable to build a template for the emulator.
Also, the version worries me about the presence of errors in 3.4.beta.
Tomorrow I will try to merge locally with my branch 3.4. I will do this blindly. Without any understanding of the template device.

I'm planning to work on this PR and some other iOS issues, but I can't really give a time frame for when it will be ready.

You should be able to use this version of PR after some modifications, but I can't name them as I haven't been following development for some time.

problem control...
remote control uses axes for dpad

I added this to my dpad block.
Otherwise, it is not possible to make smooth control of the remote control.
The second generation console always uses two vectors.
Therefore, counting the pressure is meaningless. If we want to emulate dpad clicks, we need to read vectors.
It is also necessary to enter deadzone.

Try dpad control in a 2D game. be surprised)

InputDefault::JoyAxis jx = {-1, gamepad.dpad.xAxis.value};
InputDefault::JoyAxis jy = {-1, -gamepad.dpad.yAxis.value}; //inverse y

OSAppleTV::get_singleton()->joy_axis(joy_id, JOY_AXIS_8, jx);
OSAppleTV::get_singleton()->joy_axis(joy_id, JOY_AXIS_9, jy);

//if axis over deadzone -0.5-0.5 - pressed button
if (jx.value < -0.5)
    OSAppleTV::get_singleton()->joy_button(joy_id, JOY_DPAD_LEFT, gamepad.dpad.left.isPressed);
elif (jx.value > 0.5)
    OSAppleTV::get_singleton()->joy_button(joy_id, JOY_DPAD_RIGHT, gamepad.dpad.left.isPressed);

tvOS unsupport NSDocumentDirectory directory.
tvOS prevents writing out of cache or NSUserDefaults

Need use NSUserDefaults (512kb limit)
Need use NSCachesDirectory
