The relevant test functions are already marked as depending on
`MBEDTLS_SSL_PROTO_TLS1_3_EXPERIMENTAL`, so there's no need
to re-state this dependency for each test case.

This is in line with how the entries of the TLS 1.3 label
structure `mbedtls_ssl_tls1_3_labels` are initialized.

`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.

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.

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.

* Moved test data to .data file
* Bundled test driver hook variables in a struct
* Style fixes

Trying to compile in the PSA accelerator test driver under MBEDTLS_TEST_HOOKS
turned out to be awkward regarding existing builds. We'll put it under a
custom (not in config.h) define instead, since it's something that only
should happen in test.

This is a more natural place for handling the drivers belonging to the
'previous' SE driver spec. It makes for a cleaner psa_crypto.c, and
potentially an easier overview of how to migrate from the old SE driver
interface to the 'opaque accelerator' interface.

Also adjusted the different makefiles accordingly.
Note: driver lifetime is currently statically defined in the header, but
this will be replaced in the future based on autogeneration of lifetime
values by a script (TBD)

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.

Use macros instead of accessing directly the key identifier
fields for coding consistency and ease maintenance.
