GDScript: Improve usability of setter chains

- Consider PackedArrays non-shared since they are copied on C++/script
  boundaries.
- Add error messages in the analyzer when assigning to read-only
  properties.
- Add specific error message at runtime when assignment fails because
  the property is read-only.
