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.

Include psa_crypto_helpers.h automatically if MBEDTLS_PSA_CRYPTO_C is

psa_crypto_helpers.h no longer defines static functions, so it can be
included anywhere without worrying about unused functions.

`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.

Make it clear that this is an abstraction of the random generator
abstraction, and not an abstraction of the PSA random generator.
mbedtls_psa_get_random and MBEDTLS_PSA_RANDOM_STATE are public-facing

Executed ./scripts/bump_version.sh --version 2.25.0 --so-crypto 6
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.

Fixes an issue where configs that had `MBEDTLS_MPI_MAX_BITS` greater than 256
but smaller than the test that was running (792 bits) the test would fail
incorrectly.

Move dependancy on `MBEDTLS_MPI_MAX_BITS` to apply to the specific test cases
which will break when `MBEDTLS_MPI_MAX_BITS` is too small. This re-enables
previous tests that were turned off accidentally.

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.

We want to test both sets of functions (ext and non-ext) in turn, so goto exit
