92fb604139 Fix mbedtls_pk_get_bitlen() for RSA with non-byte-aligned sizes
Add non-regression tests. Update some test functions to not assume that
byte_length == bit_length / 8.

8174662b64 pk: implement non-PSA mbedtls_pk_sign_ext()
This makes the function always available with its
its implementation depending on MBEDTLS_USE_PSA_CRYPTO.

Related dependencies and tests are updated as well.

Fixes #7583.

564bc1bb96 Fix limitation in checking supported alg in pk_sign
The recent changes in pkparse made it so ECDSA (deterministic or not) is
set as the secondary alg and ECDH the first one. This broke the wrapper
in pk_wrap as it was only checking the first alg when deciding whether
to use deterministic or not. The wrapper should not have unnecessary
requirements on how algs are set up, so make the check more flexible.

430a4f3968 rsa_signature: Use heap memory to allocate DER encoded RSA private key
'mbedtls_pk_psa_rsa_sign_ext' function allocates a buffer of maximum
size 5679 bytes (MBEDTLS_PK_RSA_PRV_DER_MAX_BYTES) on the stack to store
DER encoded private key. This increased stack usage significantly for
RSA signature operations when MBEDTLS_PSA_CRYPTO_C is defined.

This issue was discovered when adding support for EAP-TLS 1.3 (rfc9190).

2be8c63af7 Create psa_util_internal.h
Most functions in psa_util.h are going to end up there (except those
that can be static in one file), but I wanted to have separate commits
for file creation and moving code around, so for now the new file's
pretty empty but that will change in the next few commits.

9efa8c4d14 pk: fix eckey_check_pair_psa
The problem was that the private key ID was destroyed even when
MBEDTLS_PK_USE_PSA_EC_DATA was enabled and of course this was
not correct.
At the same time the code has been slighlty reorganized to make
it more readable.

b536126183 pk: manage allocate and free space when working with PSA private key
Allocation does not need to perform any action since the priv_id field
is already present on the pk_context.
Free should destroy the key. Of course this is true only if the key
is not opaque (because in that case it's the user responsibility
to do so).
