Formatting Objective-C and Objective-C++

[louwers]

Include Objective-C and Objective-C++ in clang-format formatting. Automatically enforced (and applied) on CI.

Changes are minimal in most files.

The only change I made to the default Google style is:

ObjCSpaceAfterProperty: true

so we have

@property (nonatomic, copy, nullable)

instead of

@property(nonatomic, copy, nullable)

~I removed the "check-public-symbol" script. It didn't account for MLN_EXPORT being on another line that is split. However, this script has little value, because it checks for the debug symbols in Mapbox.h. This umbrella header is only included for backward compatibility. The auto-generated MapLibre.h umbrella header should be used.~

Never mind, we still need that, it just needs to also check the auto-generated header. I am making sure MLN_EXPORT works and that the script is updated.
