3b71bd7326 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

16514f93f0 refactor (test_utils)!: separate file for memory check functions
Memory check (leaks and heap tracing) functions for unit tests
now have a separate file now and are renamed for more consistency.

BREAKING CHANGE: renamed memory check function names which may be used
                 in unit tests outside IDF.

4375f888fa esp-tls: Fix wolfssl error codes for WANT_READ/WANT_WRITE
wolfSSL error codes are mostly positive numbers, but esp-tls potentially
non-block API (read/write) returns ssize_t, i.e. bytes read/written if
>0, errorcode otherwise. To comply with this API we have to conditionate
the wolfssl return codes to negative numbers, preferably the same codes
as mbedTLS codes.

391d7bf271 tcp_transport: Add TCP transport connection errors
Transport's error_handle is used to capture different types of errors
including esp_err_t from esp-tls and socket/system errors.
This change adds the following error codes for TCP transport:
* connection closed by a FIN flag (clean closure from server)
* DNS resolution problem
* connection timeout
These errors are already defined in esp-tls component and since this
component will be used in the future for both TCP and SSL transport, we
currently report these issues in transport::error_handle::esp_tls_last_error
of standard esp error type (esp_err_t)

be refreshed periodically to keep TLS connection intact.

b7cca3c414 Feature: Support for global CA store.
Added a new API esp_tls_set_global_ca_store(esp_tls_cfg_t *cfg) which creates a global_cacert which can be used by multiple connections by setting the use_global_ca_store variable to true in their respective structure of esp_tls_cfg_t. Also changed the cacert in the structure of esp_tls_t to a pointer.
