Revert add createOverlaySurface JNI #19040

[blasten]

Reverts #19040

Setting g_create_overlay_surface_method multiple times and looking up Java method with incorrect signature:

 g_create_overlay_surface_method = env->GetMethodID(
      g_flutter_jni_class->obj(), "createOverlaySurface", "()V");

  if (g_create_overlay_surface_method == nullptr) {
    FML_LOG(ERROR) << "Could not locate createOverlaySurface method";
    return false;
  }

The correct signature is ()Lio/flutter/embedding/engine/FlutterOverlaySurface;.

Can we get add a one line summary of the cause of the revert?

@chinmaygarde done.

@godofredoc fyi. The presubmit with the Android emulator would have caught this one.
