Raghunandan Bhat b13341fa23 MDEV-38971: ASAN/UBSAN errors, assertion is_valid_value_slow() failure upon combination temporal functions and ZERO_DATE_TIME_CAST

Problem:
  The following functions-
  - `Item_func_last_day::get_date`
  - `Item_date_typecast::get_date`
  - `Item_datetime_typecast::get_date` forwarded the TIME_INTERVAL_DAY /
  TIME_INTERVAL_hhmmssff flags, set by an enclosing EXTRACT, into the
  DATE/DATETIME conversion of their argument.This made, for ex:
  LAST_DAY(200012010000) and CAST(200012010000 AS DATETIME) parse number
  as TIME interval instead of a DATETIME. Under ZERO_DATE_TIME_CAST
  that hour became an out-of-range month, overflowing days_in_month in
  `check_date` and invalidating the Datetime.

Fix:
  A DATE / DATETIME can never be an interval, so suppress the
  TIME_INTERVAL_hhmmssff / TIME_INTERVAL_DAY flags when `LAST_DAY` and
  `CAST` converts its argument. Also add a debug assert in `check_date`
  to catch any future caller that violates its "month is assumed valid"
  contract.
