MDEV-27452 TIMESTAMP(0) system field is allowed for certain creation of system-versioned table

Browse Source 
First, we do not add VERS_UPDATE_UNVERSIONED_FLAG for system field and
that fixes SHOW CREATE result.

Second, we have to call check_sys_fields() for any CREATE TABLE and
there correct type is checked for system fields.

Third, we update system_time like as_row structures for ALTER TABLE
and that makes check_sys_fields() happy for ALTER TABLE when we make
system fields hidden.
