RMT refactoring based on IDF (#6024)

Browse Source 
Summary

RMT HAL refactoring based on IDF.

Impact

Improves RMT by adding IDF v4.4 support.
Receiving RMT can handle any size of data.
rmtInit() has a new parameter - RxBufferSize - to hold any number of data when receiving RMT.
rmtWrite() has a new parameter - wait_tx_done - to block writing until sending all data.
