`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.

For now, only instrument the one function for which buffer copying has been
implemented, namely `psa_cipher_encrypt`.

The new script `tests/scripts/generate_psa_wrappers.py` generates the
implementation of wrapper functions for PSA API functions, as well as a
header that defines macros that redirect calls to the wrapper functions. By
default, the wrapper functions just call the underlying library function.
With `--log`, the wrapper functions log the arguments and return values.
This commit only introduces the new script. Subsequent commits will
integrate the wrappers in the build.
