IMPALA-15481: Calcite planner: Add NVL2 support

Rewrite unqualified NVL2 calls to IF with an IS NOT NULL selector,
reusing IF validation and coercion.

Tests: 20 Maven methods and 19 direct compiler cases on TY-01.
Combined with 25004, 25006, 25009 and 25014: 44 Maven methods and
171 strict HS2 executions. HS2 uses native 2f022a5, codegen disabled.
