This fixes the ability to exercise keys in configurations where MD5 is
supported for direct use, but not inside some accelerated algorithms. This
is the case in `all.sh test_psa_crypto_config_accel_ecc_ecp_light_only` and
some other accelerated-ECC components of `all.sh`, where the driver is built
without MD5 support but built-in MD5 remains enabled.
This is only a hack, not a theoretically correct fix, but a correct fix is
out of scope of my current work.

Parsing a key and importing it into PSA may result in a policy that
specifies an algorithm that is not included in the build. This happens if
the key type is supported, but not the algorithm, e.g. in a build with
MBEDTLS_ECP_C but not MBEDTLS_ECDSA_C.

These functions are thread safe, but using them from within multiple
threads at the same time may not have the intended effect, given order
cannot be guaranteed. Also, standardise header comment formatting.

This option causes nested calls to PSA functions, so is not compatible
with memory poisoning as it currently stands.

`gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
detected minor infelicity in `calloc()` API usage in `mbedtls`:

Remove the use of extern and instead use an accessor to get the address
of the test info mutex (defined only if MBEDTLS_TEST_MUTEX_USAGE is
defined, to hopefully stop more general usage)

Only mbedtls_test_opaque_unwrap_key() is actually needed by other
test drivers to deal with opaque keys. mbedtls_test_opaque_wrap_key()
can be kept private to test_driver_key_management.c.

Make sure that extra UNPOISON calls do not cause the poisoning counter
to underflow and wrap around.
Memory that is unpoisoned multiple times should remain unpoisoned.

This allows unusually-nested memory poisoning to work correctly, since
it keeps track of whether any buffers are still poisoned, rather than
just disabling poisoning at the first call to the UNPOISON() macro.

`psa_collect_statuses.py` runs `make RECORD_PSA_STATUS_COVERAGE_LOG=1`,
which builds with `RECORD_PSA_STATUS_COVERAGE_LOG`. In this mode, the build
includes wrappers for PSA functions, which conflict with the newly
introduced wrappers that are enabled whenever `MBEDTLS_TEST_HOOKS` is
enabled. In the future, the collect-statuses mechanism should use the new
generic wrapper mechanism. For the time being, keep the old wrappers and
avoid the new wrappers when doing the collect-statuses build.

Code in unit tests (`tests/suites/*.function`) and in test support
code (`tests/src/**.c`) will now go through the wrapper functions when they
call a PSA API function and `MBEDTLS_TEST_HOOKS` is enabled.

Commit files generated by `tests/scripts/generate_psa_wrappers.py`. As of
this commit, the new code is neither useful (the wrappers just call the
underlying functions) nor used (the wrapper functions are not called from
anywhere). This will change in subsequent commits.
This is a deviation from our normal practice of generating
configuration-independent platform-independent files as part of the build in
the development branch. The PSA test wrappers will be committed to the
repository for some time for two reasons:
* In the short term, we will review the generated code but not fully review
the generator script.
* The build scripts cannot yet accommodate a generated header file.

Allow memory poisoning to be enabled and disabled at runtime using a
thread-local flag. This allows poisoning to be disabled whenever a PSA
function is called but not through the test wrappers, removing false
positive use-after-poisons.
