5928a87aa7 feat(mbedtls): Add configuration to control dynamic buffer strategy in mbedtls
Problem:
1. In low-memory scenarios, the dynamic buffer feature can fail due to memory fragmentation.
2. It requires a contiguous 16KB heap chunk, but continuous allocation and deallocation of
the RX buffer can lead to fragmentation.
3. If another component allocates memory between these operations, it can break up the
available 16KB block, causing allocation failure.

Solution:
1. Introduce configurable strategy for using dynamic buffers in TLS connections.
2. For example, convert RX buffers to static after the TLS handshake.
3. Allow users to select the strategy via a new field in the esp_http_client_cfg_t structure.
4. The strategy can be controlled independently for each TLS session.

90290507fb fix(mbedtls): Build issue in dynamic buffer feature
Fix build issue in mbedTLS dynamic buffer feature with
`CONFIG_MBEDTLS_DHM_C` enabled case. Also added a build
configuration for the test coverage.

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
- 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- Fixed outdated function prototypes and usage in mbedlts/port/aes/esp_aes_gcm.c due to changes in GCM module

1c9592efc4 fix(mbedtls): fix mbedtls dynamic resource memory leaks and RSA cert drop earlier
RX process caches the session information in "ssl->in_ctr" not in "ssl->in_buf".
So when freeing the SSL, can't free the "ssl->in_ctr", because the "ssl->in_buf"
is empty.

Make the RX process like TX process, and cache the session information in
"ssl->in_buf", so that the cache buffer can be freed when freeing the SSL.
