希望能够支持kotlinx-datetime的时间类

[sidian123]

kotlinx-datetime是kotlin版本的日期时间库，希望能够支持以下类：

kotlinx.datetime.LocalDateTime kotlinx.datetime.LocalDate kotlinx.datetime.LocalTime

虽然可以自定义以下SqlType实现，但更适合集成到ktorm的库里（包括ksp）：

import kotlinx.datetime.LocalDateTime
import kotlinx.datetime.LocalDate
import kotlinx.datetime.LocalTime

/**
 * [SqlType] implementation represents `datetime` SQL type.
 */
public object LocalDateTimeSqlType : SqlType<LocalDateTime>(Types.TIMESTAMP, "datetime") {

    override fun doSetParameter(ps: PreparedStatement, index: Int, parameter: LocalDateTime) {
        ps.setTimestamp(index, Timestamp.valueOf(parameter.toJavaLocalDateTime()))
    }

    override fun doGetResult(rs: ResultSet, index: Int): LocalDateTime? {
        return rs.getTimestamp(index)?.toLocalDateTime()?.toKotlinLocalDateTime()
    }
}

/**
 * [SqlType] implementation represents `date` SQL type.
 */
public object LocalDateSqlType : SqlType<LocalDate>(Types.DATE, "date") {

    override fun doSetParameter(ps: PreparedStatement, index: Int, parameter: LocalDate) {
        ps.setDate(index, Date.valueOf(parameter.toJavaLocalDate()))
    }

    override fun doGetResult(rs: ResultSet, index: Int): LocalDate? {
        return rs.getDate(index)?.toLocalDate()?.toKotlinLocalDate()
    }
}

/**
 * [SqlType] implementation represents `time` SQL type.
 */
public object LocalTimeSqlType : SqlType<LocalTime>(Types.TIME, "time") {

    override fun doSetParameter(ps: PreparedStatement, index: Int, parameter: LocalTime) {
        ps.setTime(index, Time.valueOf(parameter.toJavaLocalTime()))
    }

    override fun doGetResult(rs: ResultSet, index: Int): LocalTime? {
        return rs.getTime(index)?.toLocalTime()?.toKotlinLocalTime()
    }
}
