Move the key buffer size calculation code under
tests to avoid check-names.sh to complain about
"likely macros with typos".
This removes the calculation of key buffer
sizes for the test driver from the wrapper based on
static size data. But the code is still there in test
code to be used when we go back to work on the
generation of the driver wrapper.

The macro always meant 'location', but was mistakenly named 'lifetime'.
Naming it location instead makes much more sense, and drives home the
conceptual differences between location and lifetime values.

Builtin key support for the test driver is always compiled in, and no
longer guarded by MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS.
Parsing the key slot from the buffer by cast and assign instead of memcmp.
For exporting keys, the test driver no longer reaches into the key
identifier in order to check whether a key is builtin, but rather
assumes so based on the key buffer length. It's the driver's
responsibility to be able to detect the key material it returned as part
of the get_builtin_key operation.

`error.c` is a file generated from `error.h` and thus cannot contain the code
that was previously added. This commit fixes that issue by moving the
`MBEDTLS_ERR_ADD` macro and associated function and function pointer into
`common.h` and `common.c`.
Also fix a typo in `tests/include/test/helpers.h` where tabs were accidentally
used instead of spaces.

Adds a macro (`MBEDTLS_ERR_ADD`) to add error codes together and check that the
result will not be corrupted. This additional check is only enabled during
testing when `MBEDTLS_TEST_HOOKS` is defined.
Also includes a reference usage example in `rsa.c` where two high-level error
codes could be incorrectly added together under the right conditions. This now
ensures that when this error occurs during testing it will be correctly
reported.

The primary goal of this commit is to fix various comments where
`clang -Wdocumentation` identified a discrepancy between the actual
function parameters and the documented parameters. The discrepancies
were due to copypasta, formatting issues or documentation that had
diverged from the implementation.

ARRAY_LENGTH has a portable but unsafe implementation, and a
non-portable implementation that causes a compile-time error if the
macro is accidentally used on a pointer.
The safety check was only implemented for __GCC__-defining compilers,
but the part that triggered the compile-time error was always used. It
turns out that this part triggers a build warning with MSVC (at least
with some versions: observed with Visual Studio 2013).
```
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): error C2220: warning treated as error - no 'object' file generated [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]

```
Since a compile-time error is never triggered when the compile-time
check for the argument type is not implemented, just use the unsafe
macro directly when there's no safety check.

This ensures that test cases won't leave persistent files behind even
on failure, provided they use TEST_USES_KEY_ID(). Test cases that
don't use this macro are unaffected.
Tests that use PSA_DONE() midway and expect persistent keys to survive
must use PSA_SESSION_DONE() instead.

If the mutex usage verification framework is enabled and it detects a
mutex usage error, report this error and mark the test as failed.
This detects most usage errors, but not all cases of using
uninitialized memory (which is impossible in full generality) and not
leaks due to missing free (which will be handled in a subsequent commit).

Make USE_PSA_INIT() and USE_PSA_DONE() available in all test suites in
all cases, doing nothing if MBEDTLS_USE_PSA_CRYPTO is disabled. Use
those in preference to having explicit

left where using the new macros would be better).
Also provide PSA_INIT() by symmetry with PSA_DONE(), functional
