refactor(rmt): function placement by tx and rx separately

 By default, the RMT interrupt is deferred when the Cache is disabled for reasons like writing or erasing the main Flash. Thus the transaction-done interrupt does not get handled in time, which is not acceptable in a real-time application. What is worse, when the RMT transaction relies on **ping-pong** interrupt to successively encode or copy RMT symbols, a delayed interrupt can lead to an unpredictable result.

 默认情况下，禁用 cache 时，写入/擦除主 flash 等原因将导致 RMT 中断延迟，事件回调函数也将延迟执行。在实时应用程序中，应避免此类情况。此外，当 RMT 事务依赖 **交替** 中断连续编码或复制 RMT 符号时，上述中断延迟将导致不可预测的结果。
