[google_maps_flutter] Update Android for non-nullable generics

Now that Pigeon supports non-nullable generics, update the Pigeon
definition to remove all the unnecessary nullability in generics.

This is largely a no-op for non-test code because these types are mostly
for passing from Dart to Java, and Java doesn't support non-nullable
generics so nothing changes on the native side.
