[#9374] fix(spark): Fix MySQL datetime filter pushdown in Spark JDBC
connector (#11451)
### What changes were proposed in this pull request?
Map MySQL `datetime` to `TimestampType` in Spark JDBC type converters to
match Spark's native JDBC behavior.
### Why are the changes needed?
Filtering on MySQL `datetime` columns fails with
`SQLSyntaxErrorException: near ':07:43)'`. Gravitino maps `datetime` to
`TimestampNTZType` (Spark 3.4+), which the MySQL JDBC dialect cannot
format as valid SQL literals. Spark's native JDBC catalog maps
`datetime` → `TimestampType` correctly.
Fix: #9374
### Does this PR introduce _any_ user-facing change?
Yes. MySQL `datetime` columns can now be used as filter predicates via
Gravitino's Spark JDBC catalog.
### How was this patch tested?
Added unit tests: `TestSparkJdbcTypeConverter`,
`TestSparkJdbcTypeConverter34`, `TestSparkJdbcTypeConverter35`.
