IMPALA-10739: Support setting new partition spec for Iceberg tables

With this patch Impala will support partition evolution for
Iceberg tables.

The DDL statement to change the default partition spec is:
ALTER TABLE <tbl> SET PARTITION SPEC(<partition-spec>)

Hive uses the same SQL syntax.

Testing:
- Added FE test to exercise parsing various well-formed and ill-formed
  ALTER TABLE SET PARTITION SPEC statements.

- Added e2e tests for:
  - ALTER TABLE SET PARTITION SPEC works for tables with HadoopTables
    and HadoopCatalog Catalog.
  - When evolving partition spec, the old data written with an earlier
    spec remains unchanged. New data is written using the new spec in
    a new layout. Data written with earlier spec and new spec can be
    fetched in a single query.
  - Invalid ALTER TABLE SET PARTITION SPEC statements yield the
    expected analysis error messages.

> Impala should support partition evolution for Iceberg tables, i.e. it should be able to set a new partition spec for an Iceberg table via DDL.
> The command should be
> {noformat}
> ALTER TABLE <tbl> SET PARTITION SPEC(<partition-spec>)
> {noformat}
> to be aligned with Hive.
