[generator] Fix xamarin-android/src/Mono.Android build (#972)
Context: a65d6fb Context: dotnet/android#6939 dotnet/android#6939 attempted to bump to 05eddd9, which promptly broke the build of src/Mono.Android, e.g. `src/Mono.Android/obj/Debug/net6.0/android-32/mcw/Android.Widget.GridLayout.cs`: /* */ partial class GridLayout { /* */ partial class partial class LayoutParams { /* */ [Register ("rowSpec")] /* */ public Android.Widget.GridLayout.Spec? RowSpec { /* */ get { /* */ const string __id = "rowSpec.Landroid/widget/GridLayout$Spec;"; /* */ var __v = _members.InstanceFields.GetObjectValue (__id, this); /* */ return global::Java.Lang.Object.GetObject<Android.Widget.GridLayout.Spec> (__v.Handle, JniHandleOwnership.TransferLocalRef); /* */ } /* */ set { /* */ const string __id = "rowSpec.Landroid/widget/GridLayout$Spec;"; /* */ IntPtr native_value = global::Android.Runtime.JNIEnv.ToLocalJniHandle (value); /* */ try { /* L 239 */ _members.InstanceFields.SetValue (__id, this, new JniObjectReference (value)); /* */ } finally { /* L 242 */ global::Android.Runtime.JNIEnv.DeleteLocalRef (value); /* */ } /* */ } /* */ } /* */ } /* */ } due to compilation errors: src/Mono.Android/obj/Debug/net6.0/android-32/mcw/Android.Widget.GridLayout.cs(239,77): error CS1503: Argument 1: cannot convert from 'Android.Widget.GridLayout.Spec' to 'System.IntPtr' src/Mono.Android/obj/Debug/net6.0/android-32/mcw/Android.Widget.GridLayout.cs(242,54): error CS1503: Argument 1: cannot convert from 'Android.Widget.GridLayout.Spec' to 'System.IntPtr' This was caused by `BoundFieldAsProperty.cs` not appropriately setting `arg` to `native_arg`, so that the correct variable would be cleaned up in the `finally` block. There was another set of errors: src/Mono.Android/obj/Release/net6.0/android-32/mcw/Android.Widget.ArrayAdapter.cs(525,53): error CS1503: Argument 1: cannot convert from 'Java.Lang.ICharSequence[]' to 'string[]?' which was also caused by a65d6fb mis-refactoring `SourceWriterExtensions.cs`, and overlooking the entire existence of the `CharSequence.ArrayToStringArray()` method (oops). Update `generator` so that xamarin-android once again builds, and add unit tests to hit these particular code paths.
