IMPALA-13267: Display number of partitions for Iceberg tables

Before this change, query plans and profile reported only a single
partition even for partitioned Iceberg tables, which was misleading
for users.
Now we can display the number of scanned partitions correctly for
both partitioned and unpartitioned Iceberg tables. This is achieved by
extracting the partition values from the file descriptors and storing
them in the IcebergContentFileStore. Instead of storing this information
redundantly in all file descriptors, we store them in one place and
reference the partition metadata in the FDs with an id.
This also gives the opportunity to optimize memory consumption in the
Catalog and Coordinator as well as reduce network traffic between them
in the future.

Time travel is handled similarly to oldFileDescMap. In that case
we don't know the total number of partitions in the old snapshot,
so the output is [Num scanned partitions]/unknown.

Testing:
 - Planner tests
 - E2E tests
   - partition transforms
   - partition evolution
   - DROP PARTITION
   - time travel
