Fix i2s probing hang (#608)

* Fix I2S stepper hung just after the completion of motor moving

* Fix recompile issue

Fixed a problem with the recompile not being recompiled even if the files under the Custom folder are changed.

* More comment for macOS in debug.ini

* Fix the timing of calling I2S out's exclusion function and reset sequence

The reset sequence did not seem to be correct, so I changed it.
According to the ESP-IDF PR, the correct sequence is as follows:
1)TX module
2)DMA
3)FIFO

* Add some comments
