Specifically: checks if a passed IntPtr is equal to IntPtr.Zero. Utilizes the same syntax as ArgumentNullException.ThrowIfNull; only the argument needs to be passed, with the argument name being automatically pulled via the CallerArgumentExpression attribute1. In addition to implementing this on the generated NativeCalls files, minor changes were also made to bindings_generator.cpp in order to give the resulting file proper formatting.

Thanks, a few minor nit-picks but looks good to me otherwise.

Builds for the .NET version on the build server fail with this error, which I believe is related to this PR:

modules/mono/glue/GodotSharp/GodotSharp/Core/NativeInterop/ExceptionUtils.cs(244,90): error CS0103: The name 'ptr' does not exist in the current context [modules/mono/glue/GodotSharp/GodotSharp/GodotSharp.csproj]

See also #82983.

Fix: #86373.
