Fixes #32365
This PR adds support for writing to dynamic Iceberg destinations, meaning that one transform instance can write to multiple Iceberg tables.
IcebergIO is offered as a Managed transform, which makes it a portable transform. Instead of offering a function of some sort, users can specify a String template and we will substitute in the appropriate record field values to determine the destination (see RowStringInterpolator for more details and examples)
For more information on portable dynamic destinations, see #32365
