sink(ticdc): fix incorrect default value for the not null timestamp field in the Debezium protocol

[wk989898]

What problem does this PR solve?

Issue Number: close #11966

What is changed and how it works?

Follow the official document https://debezium.io/documentation/reference/3.0/connectors/mysql.html#mysql-temporal-types.

• For TIMESTAMP columns whose default value is specified as CURRENT_TIMESTAMP or NOW, the value 1970-01-01 00:00:00 is used as the default value.
• MySQL allows zero-values for DATE, DATETIME, and TIMESTAMP columns because zero-values are sometimes preferred over null values. The MySQL connector represents zero-values as null values when the column definition allows null values, or as the epoch day when the column does not allow null values.
