New statement hint LOCK_SCANNED_RANGE is introduced to allow client transaction to request an exclusive lock on a set of ranges scanned by a transaction. This statement hint could be applied to both SELECT and UPDATE statements.

However, the current StatementParser only allow statement hints to exist in SELECT statement but not in UPDATE statements. Doing so in UPDATE statements will result in the following exception:

com.google.cloud.spanner.jdbc.JdbcSqlExceptionFactory$JdbcSqlExceptionImpl: INVALID_ARGUMENT: Unknown statement: @{LOCK_SCANNED_RANGES=exclusive} UPDATE ...

Need to update the StatementParser to include support to this new hint in UPDATE statements.
