Pack enums in StyleGridItemData as bit fields.

This patch changes StyleGridItemData::auto_repeat_columns_type_ and
auto_repeat_rows_type_ into bit fields. It also moves the declaration of
grid_auto_flow_ to be with the other bit fields so that they can be
packed together.

This reduces the size of StyleGridItemData by 8 bytes.
