change(mbedtls/port): optimize gcm_mult()
...
1) pre-shift GCM last4 to use 32-bit shift
On 32-bit architectures like Aarch32, RV32, Xtensa,
shifting a 64-bit variable by 32-bits is free,
since it changes the register representing half of the 64-bit var.
Pre-shift the last4 array to take advantage of this.
2) unroll first GCM iteration
The first loop of gcm_mult() is different from
the others. By unrolling it separately from the
others, the other iterations may take advantage
of the zero-overhead loop construct, in addition
to saving a conditional branch in the loop.

fix(mbedtls/gcm): Add support for software fallback for non-AES ciphers in a GCM operation
...
- Even if the config MBEDTLS_HARDWARE_AES is enabled, we now support fallback
to software implementation of GCM operations when non-AES ciphers are used.

fix(mbedtls): Fixed the transmission of return values of the esp-aes APIs
...
- Earlier, some intermediate return values were not stored and returned,
thus incorrect return values used to get transmitted to the upper layer of APIs.
- Also, zeroised the output buffer in case of error condition.

mbedtls: GCM implementation is replaced with CTR-based calculation
...
- GCM operation in mbedtls used ECB, which calculated only 16 bytes of data each time.
- Therefore, when processing a large amount of data, it is necessary to frequently set hardware acceleration calculations,
- which could not make good use of the AES DMA function to improve efficiency.
- Hence, GCM implementation is replaced with CTR-based calculation which utilizes AES DMA to improve efficiency.

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
