stiga-huang 9bb7157bf0 IMPALA-10387: Add missing overloads of mask functions used in Ranger default masking policies ...

The mask functions in Hive are implemented through GenericUDFs which can
accept an infinite number of function signatures. Impala currently don't
support GenericUDFs. So we provide builtin mask functions with limited
overloads.

This patch adds some missing overloads that could be used by Ranger
default masking policies, e.g. MASK_HASH, MASK_SHOW_LAST_4,
MASK_DATE_SHOW_YEAR, etc.

Tests:
 - Add test coverage on all default masking policies applied on all
   supported types.
