Developed RMT support for Esp32s3

[GarmischWg]

• Copied StepperISR_esp32c3_rmt.cpp to StepperISR_esp32s3_rmt.cpp
• renamed registers at StepperISR_esp32s3_rmt.cpp
• updated defines related to esp32s3 in fas_common.h
• updated parts of readme related to esp32s3
• find and replace "c3" to "s3" for the inline comments in StepperISR_esp32s3_rmt.cpp

Tested with 6 steppers only, with a shared enable pin. I don't have 8 steppers.

Only line 2 in StepperISR_esp32_rmt.cpp is intentionally changed, the other changes is caused by the auto formatter.

Thanks for the PR.

Apparently the espressif lib has been updated and now causing a build error on github actions. I really need to fix it to a specific release in platformio.ini for all esp32 targets and not only some. And need to change the title in build_examples_esp32.yml

FYI, my setup:

• platformio 6.1.13
• esp32 idf: 6.4.0

for this setup, compilation was successful for esp32s3

From what i saw, it is just a warning, saying that a function in esp32-hal-uart.c should return bool instead of void. But we didn't write that function.... It is inside arduinoespressif32 framework. Is it possible to ignore that warning?

I will deal with it in a couple of days. for now I will just merge it, so you do not need to wait.

it is ok, i prefer that the development is not rushed, i can just use my local updated version of fastAccelLibrary first.

If people suddenly start raising issues about the new update, just revert it. (Hopefully this doesn't happen).

Your rmt driver is now included in 0.30.11. Thanks for the patch
