Class.GetHandle(Type?) already handles null input by returning NativeHandle.Zero, making the x is null ? IntPtr.Zero : Class.GetHandle(x) ternary patterns unnecessary.

`Class.GetHandle(Type?)` already handles null input by returning `NativeHandle.Zero`, making the `x is null ? IntPtr.Zero : Class.GetHandle(x)` ternary patterns unnecessary.

Pull request overview

This PR simplifies several UIKit/AppKit convenience APIs by removing redundant null checks before calling ObjCRuntime.Class.GetHandle (Type?), relying on GetHandle’s built-in null handling (returns a zero handle) to preserve existing behavior.

Changes:

  • Replaced type is null ? IntPtr.Zero : Class.GetHandle (type) patterns with Class.GetHandle (type) across several registration helpers.
  • Simplified popover background view type setters to assign the handle directly via Class.GetHandle.
