SNOW-1003959: Implement toString() in SnowflakePreparedStatementV1

[sfc-gh-wfateem]

Invoking the PreparedStatement's toString() method will now return the actual SQL query and
query ID if available rahter than the object's hashCode. This is helpful when using features
in frameworks like Spring Boot to monitor and log information about slow running queries.
