This PR implements support for "dynamic" partition columns. These are partition columns that are generated at runtime during partition overwrite/insert/etc. (i.e. write operations). This allows users to partition a table in a finer-grained manner than was previously possible.
Prior to this change, materialized views, loosely speaking, could only be partitioned on expressions derived from partition columns of other tables. This restriction is now only placed on the "static" partition columns, which must be a prefix of the full list of partition columns.
