In ESP32-S3 flat build with USER_HEAP mode, ROM strdup internally calls
malloc which may be mapped to a different heap than lib_free, causing
cross-heap allocation issues and system crashes.
This commit adds a new Kconfig option ESP32S3_DONT_USE_ROM_LIBC to
allow using NuttX libc instead of ROM newlib functions. When USER_HEAP
mode is selected, this option is automatically enabled.
