In macro_collector.py, base InputsForTest on PSAMacroEnumerator rather
than PSAMacroCollector. It didn't make much sense to use
PSAMacroCollector anymore since InputsForTest didn't use anything
other than the constructor.
psa_generate_tests now generates arguments for more macros.
In particular, it now collects macro arguments from
test_suite_psa_crypto_metadata. Algorithms with parameters are now
supported.

In generate_psa_tests, use InputsForTest rather than PSAMacroCollector
to gather values. This way, the enumeration of values to test includes
values used in metadata tests in addition to constructors parsed from
header files. This allows greater coverage of values built from
constructors with arguments. This doesn't make a difference yet, but
it will once algorithm constructors with arguments are supported in
generate_psa_tests.
Make the injection of numerical values optional. They are useful for
test_psa_constant_names, so keep them there. Don't use them for
not-supported tests: they might make sense, but the current code
wouldn't work since it doesn't know how to make up fake key material
or what dependencies to generate. Don't use them for storage tests:
they only make sense for supported values.
Don't inject 'PSA_SUCCESS': that's superfluous.

Add a missing guard for the definition and declaration of
mbedtls_test_hook_error_add.
Also make the declaration always visible when MBEDTLS_TEST_HOOKS is
enabled. This fixes an issue when MBEDTLS_ERROR_C is not defined but
MBEDTLS_TEST_HOOKS is.

Fix unused parameter warnings when MBEDTLS_TEST_HOOKS is not enabled.
A few issues were caught by check-names.sh namely:
- mbedtls_error_add was not capitalised.
- mbedtls_test_hook_error_add was being defined multiple times as the
definition was in a header.

The previous implementation of the error addition interface did not comply
with the invasive testing architecture guidelines. This commit fixes that
by:
- Renaming functions/macros/variables to follow the mbedtls_error_xxx or
mbedtls_test_hook_xxx convention.
- Making mbedtls_test_hook_error_add a global variable that can be set
by the testing code.
- Using a static inline function call, as opposed to macro, to keep
discrepancies between debug and production version to a minimum.

Change the signature of the `hook` parameter of `mbedtls_set_err_add_hook`
to use the actual signature of the function as opposed to `void *`. This
fixes a warning when compiling with clang `-pedantic`.

`error.c` and error.h are the more logical place to keep this code and it
prevents issues with building `common.c` and conflicts with other projects
that use mbedtls (such as mbedOS).
`error.c` has been automatically generated by first adding the code to
`error.fmt` and then running `./scripts/generate_errors.pl`.
Also add parenthesis to the addition in `MBEDTLS_ERR_ADD`.

Add the test keys from RFC 8032 (§7.1 Ed25519 "TEST 1", §7.4 Ed448 "Blank").

Construct an object given the attributes and material for a PSA crypto key
and get the Mbed TLS storage representation.
The code to generate the storage representation was written based on the
specification in docs/architecture/mbed-crypto-storage-specification.md,
without looking at the code.
The data in the unit tests is from the AES-128 format_storage_data_check
test case in test_suite_psa_crypto_persistent_key.data, tweaked manually.
This commit creates a basic framework for using symbolic values for
attributes, but does not yet implement obtaining the corresponding numerical
values from an external source.

There are type annotations that indirectly depend on the
typing_extensions module (on Python 3.5-3.7: Protocol was added to the
core typing module in 3.8). The typing_extensions module is not
installed by default, so the code didn't run on a pristine Python
installation.
To avoid depending on a non-default module, make the dependency on
typing_extensions optional. (It's still required to run mypy, but
installing mypy takes care of providing typing_extensions.) If it
isn't available, provide a substitute definition that's just good
enough to get the scripts to run.
Move this ugly code to its own module to avoid the temptation of
spreading such ugliness all over the place. It's likely to be used in
other modules anyway.

Asymmetric keys can't just be arbitrary byte strings: the public key
has to match the private key and the private key usually has
nontrivial constraints.
In order to have deterministic test data and not to rely on
cryptographic dependencies in the Python script, hard-code some test
keys.
In this commit, copy some test keys from test_suite_psa_crypto.data.
