feat(sha): add sha_hal_is_sm3_supported()

Report whether the SHA peripheral can run the SM3 mode. The LL function
sha_ll_is_sm3_supported() exists on every chip. ESP32-S31 reads the
DIS_SM_CRYPT eFuse, which disables SM2 and SM3 permanently. ESP32-C5 and
ESP32-H4 have SM3 but no such eFuse. All other chips have no SM3.
