IntegerField / BigDecimalField .clear sets state to invalid

[h-huss]

Description

When calling IntegerField.clear or BigDecimalField.clear, the component is marked as invalid

This seems to be related to #4833 and vaadin/web-components#5410

Expected outcome

The component should remain valid, as null is an acceptable value

Minimal reproducible example

@Route("test")
public class TestView extends VerticalLayout {
  public TestView() {
    DatePicker datePicker = new DatePicker();
    IntegerField intField = new IntegerField();
    DateTimePicker dtp = new DateTimePicker();
    BigDecimalField bdf = new BigDecimalField();
    Button clear = new Button("Clear", event -> {
      datePicker.clear(); // Clears OK
      intField.clear(); // Invalid
      dtp.clear(); // Clears OK
      bdf.clear(); // Invalid
    });
    add(datePicker, intField, dtp, bdf, clear);
  }
}

Steps to reproduce

1. Fill the fields
2. Click clear
3. IntegerField and BigDecimalField will become invalid

Workaround is the same as in #4833: Call setValue(null) twice.
