Declare all AES and DES functions that return int as needing to have
their result checked, and do check the result in our code.
A DES or AES block operation can fail in alternative implementations of
mbedtls_internal_aes_encrypt() (under MBEDTLS_AES_ENCRYPT_ALT),
mbedtls_internal_aes_decrypt() (under MBEDTLS_AES_DECRYPT_ALT),
mbedtls_des_crypt_ecb() (under MBEDTLS_DES_CRYPT_ECB_ALT),
mbedtls_des3_crypt_ecb() (under MBEDTLS_DES3_CRYPT_ECB_ALT).
A failure can happen if the accelerator peripheral is in a bad state.
Several block modes were not catching the error.
This commit does the following code changes, grouped together to avoid
having an intermediate commit where the build fails:
* Add MBEDTLS_CHECK_RETURN to all functions returning int in aes.h and des.h.
* Fix all places where this causes a GCC warning, indicating that our code
was not properly checking the result of an AES operation:
* In library code: on failure, goto exit and return ret.
* In pkey programs: goto exit.
* In the benchmark program: exit (not ideal since there's no error
message, but it's what the code currently does for failures).
* In test code: TEST_ASSERT.
* Changelog entry.

Now that support for earlier version have been removed, we no longer

Since TLS 1.3 is being gradually introduced, we might still need a
version check in some places - but here the function is called
ssl_tls12_populate_tranform() and TLS 1.3 has its own function
mbedtls_ssl_tls13_populate_transform(), so when this function is called
we just know we're using TLS 1.2.

MULADDC_CORE reads from (%%rsi) and writes to (%%rdi). This fragment is
repeated up to 16 times, and %%rsi and %%rdi are s and d on entry
respectively. Hence the complete asm statement reads 16 64-bit words
from memory starting at s, and writes 16 64-bit words starting at d.
Without any declaration of modified memory, Clang 12 and Clang 13 generated

This parameter was set but not used, which was pointless. Clang 14 detects
this and legitimately complains.
Remove the parameter. This is an internal function, only called once. The
caller already has a sufficient check on the output buffer size which
applies in more cases, so there is no real gain in robustness in adding the
same check inside the internal function.
