Add carriage return support to Serial Monitor

[johonline1]

Describe the request

When outputting running values ​​to the serial monitor, either the screen scrolls upwards or the line becomes infinitely long.

When outputting to PuTTY, the last line can be continuously overwritten using the ASCII code 13 . This results in continuously updated values ​​in the last line.

Hi @johonline1. Thanks for taking the time to submit an issue.

I see we already had prior requests for this or similar features, which were declined:

• Terminal escape code support in Serial Monitor Arduino#9102
• Proper handling of CR/LF in serial monitor [imported] Arduino#346
• Serial monitor does not honor some characters Arduino#3654

There is a different take on adding such support here: #406
