Reimplement DRIVER_MCPWM_PCNT on ESP32S3

[dronus]

On newer ESP32 Frameworks ("idf5", "idf6") DRIVER_MCPWM_PCNT is not available - I guess that is because the used interface is deprecated in the Framework now.

Without DRIVER_MCPWM_PCNT queues we can only drive 4 motors in total however. Using both DRIVER_MCPWM_PCNT and RMT drivers would allow for 8 again.

So maybe DRIVER_MCPWM_PCNT can be implemented on top of the new interface?

Two more motors will be available using the two I2S-modules of the ESP32S3 in the upcoming v1.0.0

the MCPWM/PCNT-combo: due to espressif changes this is now like developing a new driver. Not on my todo-list. Volunteers welcome.
