feat(core): make micropartition streamable over tables

[universalmind303]

Description

makes Micropartition streamable over Table, and makes Table a bit cheaper to clone by wrapping the columns column in an Arc.

The driving force for these changes is that currently the logic to go from micropartition to table does not work nicely withing a streaming context as the get_tables method returns Arc<Vec<Table>>. So you can't easily chain streaming methods when working with micropartitions and tables.
