…s in `castTIMESTAMP_utf8` and `castTIME_utf8` (apache#48867) ### Rationale for this change Fixes apache#48866. The Gandiva precompiled time functions `castTIMESTAMP_utf8` and `castTIME_utf8` currently reject timestamp and time string literals with more than 3 subsecond digits (beyond millisecond precision), throwing an "Invalid millis" error. This behavior is inconsistent with other implementations. ### What changes are included in this PR? - Fixed `castTIMESTAMP_utf8` and `castTIME_utf8` functions to truncate subseconds beyond 3 digits instead of throwing an error - Updated tests. Replaced error-expecting tests with truncation verification tests and added edge cases ### Are these changes tested? Yes ### Are there any user-facing changes? No * GitHub Issue: apache#48866 Authored-by: Arkadii Kravchuk <arkadii.kravchuk@dremio.com> Signed-off-by: Sutou Kouhei <kou@clear-code.com>
