Iceberg: Add support for altering PK

1. Allow schema evolution affecting identifier-field-ids (e.g. rename or drop a column that is also a PK)
2. Allow changing the identifier-field-ids once the table is created (e.g. add or remove a column to the PK)

Hive already supports those commands, we just need to update `identifier-field-ids`

alter table tbl_ice add constraint pk1 primary key (a) disable novalidate rely;
alter table tbl_ice drop constraint pk1;
