* Replaced all C++ exception related functions with wrappers if -fno-exception is used. This prevents linking of the corresponding code in libgcc. The code size will decrease by around 7-9 KB when building with -fno-exception. * added no except test app Closes https://github.com/espressif/esp-idf/pull/5380 Closes https://github.com/espressif/esp-idf/issues/5363 Closes https://github.com/espressif/esp-idf/issues/5224 Closes IDFGH-3153 Closes IDF-2577
