MDEV-29540 Incorrect sequence values in INSERT SELECT

Browse Source 
The population of default values in INSERT SELECT was being
performed twice. With sequences, this resulted in every
second sequence value being used.

With SELECT INSERT we remove the second invokation of
table->update_default_fields(). This was already performed
in store_values() invoking fill_record_n_invoke_before_triggers()
which invoked update_default_fields() previously.

We do need to return an error on duplicate values, so the
::store_values is extended to take the ignore option.
