[.NET/CoreVideo] Use [UnmanagedCallersOnly] instead of [MonoPInvokeCallback] Partial Fix for #10470

[stephen-hawley]

straightforward

Not a big deal, but I think you can use System.Runtime.InteropServices.Unsafe.Unsafe.AsRef<T> here:

https://github.com/xamarin/xamarin-macios/blob/6590c113e47abd969d636b0d9c00769fa371a110/src/Security/SslConnection.cs#L103

so it becomes something like:

Suggested change

	var returnValue = func (delegateDisplayLink, ref tempInNow, ref tempInOutputTime, flagsIn, ref tempFlagsOut);
	var returnValue = func (delegateDisplayLink, ref System.Runtime.CompilerServices.Unsafe.AsRef<CVTimeStamp> (inNow), ...);

and that way you wouldn't have to create the temporary variables.

I looked this over in SharpLab and it looks like a win.
