42649d9270 Fix NULL+0 undefined behavior in ECB encryption and decryption 
psa_cipher_encrypt() and psa_cipher_decrypt() sometimes add a zero offset to
a null pointer when the cipher does not use an IV. This is undefined
behavior, although it works as naively expected on most platforms. This
can cause a crash with modern Clang+ASan (depending on compiler optimizations).

This requires making this function public. This will have to be solved while adding driver dipatch for EC-JPAKE.

e9b55929dc Remove useless platform macro redefinitions: automatic part 
Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.

This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')

08d34b8693 Add an EC J-PAKE KDF to transform K -> SHA256(K.X) for TLS 1.2 
TLS uses it to derive the session secret. The algorithm takes a serialized
point in an uncompressed form, extracts the X coordinate and computes
SHA256 of it. It is only expected to work with P-256.

3e56130fb9 psa_raw_key_agreement: return BUFFER_TOO_SMALL when warranted 
psa_raw_key_agreement() returned PSA_ERROR_INVALID_ARGUMENT instead of
PSA_ERROR_BUFFER_TOO_SMALL when the output buffer was too small for ECDH,
the only algorithm that is currently implemented. Make it return the correct
error code.

The reason for the wrong error code is that ecdh.c returns
MBEDTLS_ERR_ECP_BAD_INPUT_DATA, presumably for similarith with dhm.c. It
might make sense to change ecdh.c to use MBEDTLS_ERR_ECP_BUFFER_TOO_SMALL,
but dhm.c doesn't have an existing BUFFER_TOO_SMALL error. To minimize the
impact of the fix, handle this in the PSA layer.

Fixes #5735.
