Improve readability of the code:
1. move common code to `ssl_internal.h` as `static inline`.
2. Add comments.
3. Use local variables for extension size.
4. Change function signature, by adding buffer size and output length.
5. Take server srtp profile out of the loop.

In the PSA crypto library, the code for verification of ECDSA is the same for
both MBEDTLS_PSA_BUILTIN_ALG_ECDSA and
MBEDTLS_PSA_BUILTIN_ALG_DETERMINISTIC_ECDSA. So, the guards should allow for
either one to enable the code blocks. The original implementation only had
the check for ECDSA. In order to make this work, config_psa.h was updated
to ensure when MBEDTLS_CRYPTO_CONFIG is disabled, the setting for DETERMINISTIC
is only updated if MBEDTLS_ECDSA_C is also enabled.

Ensure that MBEDTLS_ECDSA_C is set when PSA_WANT_ALG_DETERMINISTIC_ECDSA
is requested. Also added MBEDTLS_ECDSA_C to the requirements comment in
config.h for MBEDTLS_ECDSA_DETERMINISTIC.

When the PSA crypto features need to be setup based on the
PSA_WANT_xxx macros, the dependent features also need to be
enabled. This change corrects that for the MBEDTLS_ECDSA_DETERMINISTIC.

The psa crypto library was generically using PSA_WANT_ALG_xxx, but
should have been using the correct MBEDTLS_PSA_BUILTIN_ALG_xxx
definition since that code is the builtin version. There were also
a couple of spots that needed to ensure the code block was enabled
for either ECDSA or DETERMINISTIC_ECDSA, not just one of them.
Fixed all the new ALG_ECDSA_DETERMINISTIC names to be
ALG_DETERMINISTIC_ECDSA instead.
Fixed test to use correct definitions.

Need to make sure the new MBEDTLS_PSA_ACCEL_XXX defines are not checked
since they should be defined by the PSA driver. Updated the list-macros.sh
script to modify the instances of those found to match the corresponding
MBEDTLS_PSA_BUILTIN_XXX that are defined in config_psa.h
Fixed definition of MBEDTLS_PSA_BUILTIN_ALG_ECDSA_DETERMINISTIC, name was
incorrect. Also fixed a missing space in the comments of crypto_config.h

Provided more detailed documentation for crypto_config.h file so it
is clear to users can enable cryptographic mechanisms using
PSA_WANT_XXX. If MBEDTLS_PSA_CRYPTO_CONFIG is not set the settings in
this file are not used.
Ensure that defines used in this file are set to 1 and not simply defined
per the specification. Also removed the __cplusplus guards since they are
not needed for this file.

Provied a more detailed description for the config_psa.h header file.
This new description makes it clear that the file should not be edited
by users or integrators. Relevant changes should be made to
psa/crypto_config.h instead.
Fixed the logic for the inclusion of MBEDTLS_PSA_BUILTIN_XXX to be set
when PSA_WANT_ALG_XXX and MBEDTLS_PSA_ACCEL_ALG_XXX is not defined,
otherwise the MBEDTLS_XXX should be set.
Ensure that MBEDTLS_PSA_BUILTIN_XXX is set to 1 and not simply defined

Provided detailed description for MBEDTLS_PSA_CRYPTO_CONFIG so that it is

With the new feature MBEDTLS_PSA_CRYPTO_CONFIG, needed to
add support that when the feature is disabled, if there
are defines like MBEDTLS_ECDSA_C defined, then the PSA_WANT_
equivalent define is also enabled. This ensures the guards in
the library psa_crypto will work properly.
Also fixed an error return code in the driver wrapper for cipher
encrypt setup so it will properly pass unit tests.
Ensured config.py full works properly with the new
MBEDTLS_PSA_CRYPTO_CONFIG, it should not be set when the full
option is used.

Originally, MBEDTLS_PSA_CRYPTO_CONFIG was being used to allow
inclusion of mbedlts/config_psa.h, but that needed to be updated
so that mbedtls/config_psa.h is always included and the definitions
specific to PSA configuration are now guarded by
MBEDTLS_PSA_CRYPTO_CONFIG. This will allow for the standard setup
to continue working while new PSA configuration items to also work.

Initial changes to PSA crypto core to support configuration
of ECDSA algorithm using PSA crypto configuration mechanism.
Guards using MBEDTLS_ECDSA_C and MBEDTLS_ECDSA_DETERMINISTIC have
been changed to be based off PSA_WANT_ALG_ECDSA and
PSA_WANT_ALG_ECDSA_DETERMINISTIC. Added new tests to all.sh to
confirm new settings are working properly. Current code does not
pass the tests since built in signature verification is not in place.

* Reworked the cipher context once again to be more robustly defined
* Removed redundant memset
* Unified behaviour on failure between driver and software in cipher_finish
* Cipher test driver setup function now also returns early when its status
is overridden, like the other test driver functions
* Removed redundant test cases
* Added bad-order checking to verify the driver doesn't get called where
the spec says it won't.

Once an operation has been 'accepted' by a driver, the remainder is bound
to the same driver, since driver-specific context structs cannot be shared.
This provides a pretty good gate mechanism for the fallback logic, too.
