[multisage][perf] do not canonicalize row when schema exactly matches

[walterddr]

we do not need to canonicalize row-by-row when v1 and v2 schema exactly matches (and requires no conversion).

The listed pass-through types are also handled in DataBlockBuilder thus it is safe to ignore the canonicalization step in leaf-stage operator; however it doesn't mean the rest of the types requires a conversion

TODO:

1. verify or optimize type-conversion logic.
2. create alternative solution for type conversion required column data types:
   • BOOL (which stored as INT)
   • TIMESTAMP (which stored as LONG)
   • ... (any other types verified)
3. possibly create the logic before reaching the leaf-stage such as doing this in COMBINE or even before COMBINE
