Allow configuring the format of EventTimeFilter

[logicoffee]

Resolves #11331

Problem

Currently, EventTimeFilter is formatted as YYYY-MM-DD HH:MM:SS+00:00. However this format is not suitable for the following cases:

referencing tables where event_time isn't of type timestamp (especially in BigQuery).
For BigQuery, it's addressed by dbt-labs/dbt-bigquery#1422.
But casting event_time to timestamp causes a full scan.
When event_time is of type date, it's preferable to filter referenced tables using event_time > 'YYYY-MM-DD'
referencing sharded tables (especially in BigQuery).
Daily sharded tables are usually have a suffix like 'YYYYMMDD'.
It's better to filter referenced tables using _table_suffix > 'YYYY-MM-DD'.

Solution

Added format configuration to EventTimeFilter.
This PR depends on dbt-labs/dbt-adapters#893.
