[enhancement](jdbc catalog) Add sqlserver jdbc url param
`useBulkCopyForBatchInsert=true` (#22032)
When useBulkCopyForBatchInsert=false, the JDBC driver will not use SQL
Server's Bulk Copy API for batch insertions. Thus, during the batch insertion
process, each insert statement needs to be individually sent to the SQL Server,
leading to a higher number of network roundtrips. Network latency could
potentially become a significant factor contributing to performance
degradation. For this reason, we recommend setting this parameter to true by
default to enhance the performance of Prepa [...]
In this manner, when performing batch insertions, the JDBC driver will send
all insertion data to SQL Server in one go via the Bulk Copy API, rather than
sending each insert statement individually. This can significantly reduce the
number of network roundtrips, thereby improving performance.
Please note that this option is only effective for fully parameterized
INSERT statements. If your INSERT statement is mixed with other SQL statements,
or if it contains values specified directly in the statement, then the JDBC
driver will not use the Bulk Copy API, but instead will use the standard insert
method.
