esp32: Add MICROPY_HW_ENABLE_UART_REPL and enable on generic S2/S3. 

Some S2/S3 modules don't use the native USB interface but instead have an
external USB-UART.  To make the GENERIC_S3/S3 firmware work on these boards
the UART REPL is enabled in addition to the native USB CDC REPL.

Fixes issues #8418 and #8524.
