Breaking event loop api change in haxe 5

[tobil4sk]

Should hx4compat have support for the old event loop api? HaxeFoundation/haxe#12388

Huh... This would require a compiler change because it's tied to something there. Other than that it should just work, I suppose. The real question if anyone actually used that API.

Lime and some lime extensions reference the old api in a couple places:

https://github.com/openfl/lime/blob/3237c405bbb98f125df58c552360856ca0c66676/src/lime/system/JNI.hx#L470C13-L470C21
https://github.com/HaxeExtension/extension-admob/blob/a961db80360027eb80905d8fc11ed04f902c4a75/extension/admob/ios/AdmobIOS.hx#L44

Yeah the idea is to remove them from Haxe 5 but we could add a haxe.MainLoop backward compatible with haxe4 and @:deprecated fields as part of hx4compat.
