samd21: Enable terse error reporting on resource constrained chip family
This reclaims over 1kB of flash space by simplifying certain exception messages. e.g., it will no longer display the requested/actual length when a fixed list/tuple of N items is needed: if (MICROPY_ERROR_REPORTING == MICROPY_ERROR_REPORTING_TERSE) { mp_raise_ValueError(translate("tuple/list has wrong length")); } else { mp_raise_ValueError_varg(translate("requested length %d but object has length %d"), (int)len, (int)seq_len); Other chip families including samd51 keep their current error reporting capabilities.
