Adds the `mbedtls_` prefix to `test_result_t` and `test_info` and updates
any references to them. This is to follow the naming convention as these are
now declared in a public namespace.

Moves the functions `test_fail`, `test_set_step`, `test_skip` and the struct
`test_info` from `tests/suites/helpers.function` to `tests/src/helpers.*`.
This is done to open these functions up to the API where they can be used by
other functions in the 'src' test infrastructure module.
As the functions are now contained within the src folder of the testing
infrastructure, the `mbedtls_` prefix has been added to the functions.

`test_fail` automatically sets `test_info.result`. This commit removes a case
where `test_info.result` was being manually set after `test_fail` was called.

TEST_ASSERT jumps to the exit label, so it must not be called from
cleanup code executed after the exit label. It's legitimate (and
indeed very common) to call PSA_DONE in cleanup code, so PSA_DONE must
not jump to exit.
Define an auxiliary function test_fail_if_psa_leaking() that calls
test_fail() with the error message provided by
mbedtls_test_helper_is_psa_leaking(). This function currently needs to
be in helpers.function rather than in a PSA-specific helper file
because it calls test_fail which is defined in helpers.function.

Don't microoptimize memory usage in tests: use separate buffers for
the input and the output. Allocate the input buffer dynamically
because the size is a parameter of the test case. Allocate the output
buffer dynamically because it's generally good practice in tests so
that a memory sanitizer can detect a buffer overflow.

When verifying the impact of a forced RNG failure, depend on the built-in
implementation of the algorithm that uses randomization, whether it's
because the algorithm is randomized or because our implementation uses
randomization for (e.g.) blinding. An external implementation could use
its own randomness source which is not affected by the forced failure of
the RNG driver.

Under MBEDTLS_ERR_RSA_RNG_FAILED, add tests where the random generator
failed. This commit tests the following operations:
* psa_generate_random()
* psa_generate_key() for a symmetric key
* Deterministic signatures that use blinding (RSA PKCS#1v1.5,
deterministic ECDSA).
* Randomized signatures (RSA PSS, randomized ECDSA).

To reduce the risk of people accidentally using the test
implementation of mbedtls_psa_external_get_random(), which is
insecure, require the user to explicitly call
mbedtls_test_enable_insecure_external_rng() first.
Disabling the test implementation of mbedtls_psa_external_get_random()
will also allow negative testing for MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG,
which will be added in a subsequent commit.

`tests/scripts/all.sh test_psa_collect_statuses` calls
`tests/scripts/psa_collect_statuses.py` which calls
`make -DRECORD_PSA_STATUS_COVERAGE_LOG` which must generate
`include/test/instrument_record_status.h`.
With the refactoring of `psa_crypto_helpers.{h,c}`, this now
needs to be done before building `psa_crypto_helpers.c`.
Also, remove `include/test/instrument_record_status.h` unconditionally
in `make clean`, which helps keep the build tree clean.

Refactor some PSA test helper functions and macros to avoid depending
on test_info and test_fail inside functions. These identifiers are
only defined in helpers.function, so they're only available in test
suites, and not in test helper modules (tests/src/*.c) which are also
linked into example programs.
This is in preparation for moving function definitions from
psa_crypto_helpers.h to psa_crypto_helpers.c.
No behavior change.

Since 349eadc58f, test_fail() reports
the first failure. So it's safe to call test_fail() again to report a
cleanup failure when we don't want to potentially erase information
about an earlier failure.
The behavior of mbedtls_test_helper_is_psa_pristine() changes if
test_info.result was neither TEST_RESULT_SUCCESS nor
TEST_RESULT_FAILED, but this should not matter since a skipped test
should not cause mbedtls_test_helper_is_psa_pristine() to fail.

Increasing the SO version of the crypto library, because the openless
API improvement came with API/ABI incompatibilities. For example
- the size of psa_key_handle_t changed
- the type of a parameter in 18 public functions has changed from
psa_key_handle_t to mbedtls_svc_key_id_t

In order to remove large buffers from the stack, the der data is written
into the same buffer that the pem is eventually written into, however
although the pem data is zero terminated, there is now data left in the
buffer after the zero termination, which can cause
mbedtls_x509_crt_parse to fail to parse the same buffer if passed back
in. Patches also applied to mbedtls_pk_write_pubkey_pem, and
mbedtls_pk_write_key_pem, which use similar methods of writing der data
to the same buffer, and tests modified to hopefully catch any future
regression on this.

Make sure that if a buffer is allowed to be empty, a null pointer is
accepted if the buffer length is 0. This was already the case for most
but not all arguments to mbedtls_cipher_auth_{en,de}crypt{,_ext}.
Make sure to pass NULL for an empty buffer in the tests.

Previously `mbedtls_mpi_exp_mod` was tested with values that were over
`MBEDTLS_MPI_MAX_SIZE` in size. This is useful to do as some paths are only
taken when the exponent is large enough however, on builds where
`MBEDTLS_MPI_MAX_SIZE` is under the size of these test values.
This fix turns off these tests when `MBEDTLS_MPI_MAX_SIZE` is too small to
safely test (notably this is the case in config-thread.h).

In two test cases, the exponentiation computation was not being fully tested
as when A_bytes (the base) == N_bytes (the modulus) -> A = N. When this is the
case A is reduced to 0 and therefore the result of the computation will always
be 0.
This fixes that issue and therefore increases the test coverage to ensure
different computations are actually being run.
