`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`.

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.

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.

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.

Change renegotiation test to use G_NEXT_SRV
to avoid problems when sending TLS 1.3
extensions since we exceed the extension
limit in G_SRV.

These tests do not specify a hash function. This is an optional parameter
with default value hmacWithSHA1, so these test cases are dependant on SHA-1
and not SHA-256
