"mbedtls_ssl_handshake_params: reorder fields to save code size" moved this
filed earlier along with byte-sized fields that should be in the 128-element
access window on Arm Thumb. This took away precious room in the 128-byte
window. Move it back further out.

Rename test driver entry points to
libtestdriver1_<name of the Mbed TLS entry point>.
This aligns with the renaming of all Mbed TLS APIs
for the test driver library (that will be put in place
in the following commits) to avoid name conflicts
when linking it with the Mbed TLS library.

Define test driver entry points that provide an alternative
to Mbed TLS driver entry points only when the PSA configuration
is used. Their purpose is only to test the PSA configuration
thus there is no good reason to use them out of this scope.

The test entry points defined in psa_crypto_hash.c
and psa_crypto_mac.c are supposed to be exact
clones of the Mbed TLS driver entry points. Thus
the operation type should be the Mbed TLS operation
type not a test one. There was no compilation error
as the hash and cipher operation test types are
currently equal to the Mbed TLS ones.

Reorder fields mbedtls_ssl_handshake_params in order to save code on Arm
Thumb builds. The general idea is to put often-used fields in the direct
access window of 128 elements from the beginning of the structure.
The reordering is a human selection based on a report of field offset and
use counts, and informed by measuring the code size with various
arrangements. Some notes:
* This is the same reordering as the corresponding commit in #5189 for 2.2x.
* I moved most byte-sized fields at the beginning where they're sure to be
in the direct access window.
* I moved buffering earlier because it can be around the threshold depending
on the configuration, and it's accessed in a lot of places.
* I moved several fields, including update_checksum and friends, early so
that they're guaranteed to be in the early access window.

Replace bitfields mbedtls_ssl_handshake_params by bytes. This saves some
code size, and since the bitfields weren't group, this doesn't increase the
RAM usage.
Replace several ints that only store values in the range 0..255 by uint8_t.
This can increase or decrease the code size depending on the architecture
and on how the field is used. I chose changes that save code size on Arm
Thumb builds and will save more after field reordering.
Leave the bitfields in struct mbedtls_ssl_hs_buffer alone: replacing them by
uint8_t slightly increases the code size.

psa_key_derivation_output_key: prioritize BAD_STATE over NOT_PERMITTED
If psa_key_derivation_output_key() is called on an operation which hasn't been
set up or which has been aborted, return PSA_ERROR_BAD_STATE. Only return
PSA_ERROR_NOT_PERMITTED if the operation state is ok for
psa_key_derivation_input_bytes() or psa_key_derivation_output_bytes() but not
ok to output a key.
Ideally psa_key_derivation_output_key() would return PSA_ERROR_NOT_PERMITTED
only when psa_key_derivation_output_bytes() is possible, but this is clumsier
to implement.

Previously passing a NULL or zero length password into either
mbedtls_pkcs12_pbe() or mbedtls_pkcs12_derive() could cause an infinate
loop, and it was also possible to pass a NULL password, with a non-zero
length, which would cause memory corruption.
I have fixed these errors, and improved the documentation to reflect the
changes and further explain what is expected of the inputs.
