Since we are applying hooks transparently to all tests, we cannot setup
and teardown test hooks in the tests. Instead we must do this in the
test wrappers which are used to pre-poison and unpoison memory.

Use the preprocessor to wrap psa_cipher_encrypt in a wrapper that
poisons the input and output buffers.

This commit
- Reverts changes previously done to psa_crypto_helpers.[c,h]
- Implements a new check for open key slots in
mbedtls_test_helper_is_psa_leaking():
- when CTR_DRBG does not use AES_C or PSA does not have an external
RNG, then we allow 1 key slot (it's the one holding the AES key)
- when the above conditions are not met, then we fallback to the
usual check for "no open key slots remaining"

When AES_C is not defined CTR_DRBG relies on PSA to get AES-ECB. This
means that, when AES-ECB is accelerated, each random operation goes through
driver access as well. This might result in unexpectedly increased
counters for driver's access.
We add extra counters in test_driver_[cipher/key_management].c to be
more specific on which driver functions are accessed and ignore
extra accesses due to CTR_DRBG.

This commit also adds AES_PSA_[INIT/DONE] in "psa_crypto_helpers.h". Its
scope is to call PSA_[INIT/DONE] only when AES_C is not defined (which is
when PSA is effectively required for CTR_DRBG).

After adding a check in ssl_conf_check(), we have configured RNG via
mbedtls_ssl_conf_rng() for TLS tests in both test_suite_ssl.function
and test_suite_debug.function. As a result, rng_get() is not only
available when MBEDTLS_SSL_HANDSHAKE_WITH_CERT_ENABLED enabled.
Therefore, we remove the guard for rng_get() to make it accessible for
TLS tests which have call for mbedtls_ssl_setup().

Asan poisons memory with an 8-byte granularity. We want to make sure that
the whole specified region is poisoned (our typical use case is a
heap-allocated object, and we want to poison the whole object, and we don't
care about the bytes after the end of the object and up to the beginning of
the next object). So align the start and end of the region to (un)poison to
an 8-byte boundary.

While an area of memory is poisoned, reading or writing from it triggers a
sanitizer violation.
Implemented for ASan.

Conflicts:
* `include/mbedtls/build_info.h`: a new fragment to auto-enable
`MBEDTLS_CIPHER_PADDING_PKCS7` was added in
c9f4040f7f3356293e90c58d11f6567def641e08 in `development-restricted`.
In `development`, this section of the file has moved to
`include/mbedtls/config_adjust_legacy_crypto.h`.
* `library/bignum.c`: function name change in `development-restricted` vs
comment change in development. The comment change in `development` is not
really relevant, so just take the line from `development-restricted`.
Since 3.0.0, mbedtls_config.h (formerly config.h) no longer needs to include
config_psa.h or check_config.h: build_info.h takes care of that.
