OVER clause converted from ZetaSQL to Logical SQL plan

[damccorm]

The OVER clause isn't supported by our ZetaSQL to Calcite translator. It can be trivially enabled in the parser with the example below, but there is some work required to convert the parsed ZetaSQL proto to Calcite logical operators (mostly in AggregateScanConverter).

This is the "over clause" TODO here: https://github.com/apache/beam/blob/243128a8fc52798e1b58b0cf1a271d95ee7aa241/sdks/java/extensions/sql/zetasql/src/main/java/org/apache/beam/sdk/extensions/sql/zetasql/translation/AggregateScanConverter.java#L147

Hi @damccorm, could you assign this to me? Thanks

[damccorm]

Sure! With https://github.com/apache/beam/pull/21719 merged you should be able to self assign with the command .take-issue though, so you should be able to do that going forward! Let me know if you run into any issues with that
