mbedtls-3.0: Fixed ESP32 build issues

- Added MBEDLTS_PRIVATE(...) wherever necessary
- For functions like mbedtls_pk_parse_key(...), it is necessary to pass the RNG function
  pointers as parameter. Solved for dependent components: wpa_supplicant & openSSL
- For libcoap, the SSLv2 ClientHello handshake method has been deprecated, need to handle this.
  Currently, corresponding snippet has been commented.
- Examples tested: hello-world | https_request | wifi_prov_mgr

mbedtls-3.0: Fixed ESP32-C3 & ESP32-S3 build issues
- Removed MBEDTLS_DEPRECATED_REMOVED macro from sha1 port
- DS peripheral: esp_ds_rsa_sign -> removed unsused 'mode' argument
- Added MBEDTLS_PRIVATE(...) wherever required

mbedtls-3.0: Fixed ESP32-S2 build issues
- Fixed outdated function prototypes and usage in mbedlts/port/aes/esp_aes_gcm.c due to changes in GCM module
