58c5cea73b Include common.h from ssl_tls13_keys.c
`common.h` takes care of the logic of chosing the correct
configuration file, so we don't need to replicate it in
each source file.

be9d6648f8 Implement TLS 1.3 key derivation function HKDF-Expand-Label
This commit introduces a new file library/ssl_tls13_key.c
which will subsequently be populated with functionality relating
to the TLS 1.3 key schedule.

Those functions are expected to be internal and are documented
in the internal header library/ssl_tls13_keys.h.

The first function to be implemented is the key expansion
function `HKDF-Expand-Label`. See the documentation in
library/ssl_tls13_keys.h for more information.

27a2688fbb Introduce public macro for maximum symmetric cipher key length
This commit introduces the public macro MBEDTLS_MAX_KEY_LENGTH,
which evaluates to an upper bound for the key lengths of all enabled
ciphers, in Bytes.

This is analogous to the already existing macros MBEDTLS_MAX_IV_LENGTH
and MBEDTLS_MAX_BLOCK_LENGTH, which provide upper bounds for the IV
and block length, respectively.

For now, MBEDTLS_MAX_KEY_LENGTH is 32 Bytes by default, and 64 in case
XTS is enabled. This is a strict overapproximation for some restricted
configurations. Ideally, the upper bound should be calculated exactly
and automatically from the list of enabled ciphers. The same applies
to the existing macros MBEDTLS_MAX_IV_LENGTH and MBEDTLS_MAX_BLOCK_LENGTH,
though, and is left for future work.

Trying to compile in the PSA accelerator test driver under MBEDTLS_TEST_HOOKS

7a2505788c Move handling of 'SE' drivers into driver wrappers
This is a more natural place for handling the drivers belonging to the

potentially an easier overview of how to migrate from the old SE driver
interface to the 'opaque accelerator' interface.

0deccf1f3e Initialize ret from test code
The test function mbedtls_mpi_lt_mpi_ct did not initialize ret in test
code. If there was a bug in library code whereby the library function
mbedtls_mpi_lt_mpi_ct() did not set ret when it should, we might have
missed it if ret happened to contain the expected value. So initialize
ret to a value that we never expect.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID
. psa_key_file_id_make to mbedtls_svc_key_id_make

27238fcbd8 psa: Use psa_key_file_id_t as the key id type
The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.

Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.

Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.

It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.

As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.

By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

`psa_key_file_id_t` was defined in `crypto_platform.h` and
not `crypto_types.h` even if it wasn't platform dependent
because back when the PSA Crypto Specification was put
together `crypto_types.h` was meant to contain only types
that were intended to make it to the specification. There
is not such constraint anymore thus move the definition
of `psa_key_file_id_t` to crypto_types.h.
