Bump to dotnet/java-interop@9dea87dc; FindClass & TypeManager (#9812)

Changes: dotnet/java-interop@f30e420...9dea87d

  * dotnet/java-interop@9dea87dc: [Java.Interop] .GetTypeSignature() supports unsigned types (dotnet/java-interop#1312)
  * dotnet/java-interop@1cfb4f4d: [generator] Add support for emitting `[UnsupportedOSPlatform]` (dotnet/java-interop#1307)

Context: #9811

The .NET MAUI template + NativeAOT currently crashes with:

	E AndroidRuntime: net.dot.jni.internal.JavaProxyThrowable: System.InvalidProgramException: InvalidProgram_Specific, IntPtr Android.Runtime.JNIEnv.monodroid_typemap_managed_to_java(System.Type, Byte*)
	E AndroidRuntime:    at Internal.Runtime.TypeLoaderExceptionHelper.CreateInvalidProgramException(ExceptionStringID, String) + 0x4c

	E AndroidRuntime:    at Android.Graphics.Drawables.LayerDrawable..ctor(Drawable[] layers) + 0xd4
	E AndroidRuntime:    at Microsoft.Maui.Platform.MauiRippleDrawableExtensions.UpdateMauiRippleDrawableBackground(View, Paint, IButtonStroke, Func`1, Func`1, Action) + 0x2ac

This appears to be related to array usage, such as
`LayerDrawable.ctor(Drawable[])` in this example.

I can reproduce the same crash using a
`ColorStateList.ctor(int[][], int[])` in `samples/NativeAOT`:

	E AndroidRuntime: net.dot.jni.internal.JavaProxyThrowable: System.InvalidProgramException: InvalidProgram_Specific, IntPtr Android.Runtime.JNIEnv.monodroid_typemap_managed_to_java(System.Type, Byte*)
	E AndroidRuntime:    at Internal.Runtime.TypeLoaderExceptionHelper.CreateInvalidProgramException(ExceptionStringID, String) + 0x4c

	E AndroidRuntime:    at Android.Runtime.JNIEnv.GetJniName(Type) + 0x1c
	E AndroidRuntime:    at Android.Runtime.JNIEnv.FindClass(Type) + 0x38
	E AndroidRuntime:    at Android.Runtime.JNIEnv.NewArray[T](T[]) + 0xa8
	E AndroidRuntime:    at Android.Content.Res.ColorStateList..ctor(Int32[][], Int32[]) + 0xdc
	E AndroidRuntime:    at NativeAOT.MainActivity.OnCreate(Bundle savedInstanceState) + 0xb8

Update `JNIEnv.FindClass(Type)` to go through `TypeManager` instead
of using `TypemapManagedToJava`.  This avoids the P/Invoke which is
causing the crash (f800c1a).

Note that we can't directly use
`JniRuntime.JniTypeManager.GetTypeSignature()`, as the previous use
of `JavaNativeTypeManager.ToJniName(Type)` would default to using
`java/lang/Object` if there was no typemap entry for `type`.

After this change, the sample works and prints a log message
indicating `ColorStateList` is created successfully:

	D NativeAOT: MainActivity.OnCreate() ColorStateList: ColorStateList{mThemeAttrs=nullmChangingConfigurations=0mStateSpecs=[[0, 1]]mColors=[0, 1]mDefaultColor=0}
