Upgrade to Calcite 1.34

Calcite 1.34 includes

1. a fix for the currently broken date_trunc function in Drill
2. support for a new QUALIFY clause in windows functions
3. incompatible core parser grammar changes that break date_diff in Drill.

Because of (3), Drill needs to make temporary use of a modified Parser.jj until Calcite backs out the mentioned parser changes. See the linked Calcite issues for more details.
