The seed file must exist before running tests. Because the location is
somewhat platform- and configuration-dependent, and to be friendly to
developers who run test suites individually and aren't familiar with this
feature, rely on the test framework code rather than on test scripts to
create the seed file.

The build option MBEDTLS_PSA_INJECT_ENTROPY requires some extra platform
functions, for historical reasons. To enable us to test this option, provide
a version of these functions for testing.
(These versions would actually work in production, but providing them in the
library in a way that doesn't break existing users might be slightly tricky,
so it's out of scope of this commit.)

Change the type of signed integer arguments from int32_t to intmax_t.
This allows the C code to work with test function arguments with a range
larger than int32_t. A subsequent commit will change the .datax generator
to support larger types.

The test framework stores size_t and int32_t values in the parameter store
by converting them all to int. This is ok in practice, since we assume int
covers int32_t and we don't have test data larger than 2GB. But it's
confusing and error-prone. So make the parameter store a union, which allows
size_t values not to be potentially truncated and makes the code a little
clearer.

During test of component build_arm_linux_gnueabi_gcc_arm5vte and
build_arm_none_eabi_gcc_m0plus. It fails with
- error: implicit declaration of function
‘test_fail_if_psa_leaking’
It happens because test_fail_if_psa_leaking is defined in
helpers.function. This block of code is not converted into C code
while compiling ssl_helpers.c. The function has been moved to
psa_crypto_helpers.c in order to fix this build error.

Since we move many functions from test_suite_ssl.function to
ssl_helpers.c in commit bd56b03. This causes various of
build errors. This commit fixes all the build errors by
- including header files
- providing function definition
- adding guards for typedef statements and functions

With this change, the renamed typedef statements (commit abfdcd8)
are moved from test_suite_ssl.function into ssl_helpers.h

test_suite_ssl.function contains many functions that are used to set
up a TLS connection. To reduce its file size, those functions would
be moved to ssl_helpers.c under tests/src. As the start of this
implementation, some necessary header files are moved in advance.

When testing under Valgrind for constant flow, skip test suites that don't
have any constant-flow annotations, since the testing wouldn't do anything
more that testing with ordinary Valgrind (component_test_valgrind).
This is a significant time saving since testing with Valgrind is very slow.
In Mbed TLS 2.28, MBEDTLS_USE_PSA_CRYPTO does not affect constant-time
functions, so testing in the full configuration covers all we need.

The bignum module does not officially support "negative zero" (an
mbedtls_mpi object with s=-1 and all limbs zero). However, we have a
history of bugs where a function that should produce an official
zero (with s=1), produces a negative zero in some circumstances. So it's
good to check that the bignum functions are robust when passed a negative
zero as input. And for that, we need a way to construct a negative zero
from test case arguments.
There are checks that functions don't produce negative zeros as output in
the test suite. Skip those checks if there's a negative zero input: we
don't want functions to _create_ negative zeros, but we don't mind if
they _propagate_ negative zeros.

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')
```

This comment (which used to be attached to the implementation, and should
not have been moved to the header file) is incorrect: the library function
mbedtls_mpi_read_string preserves leading zeros as desired, but does not
create a zero-limb object for an empty string.

Deduce MBEDTLS_PSA_ACCEL_KEY_TYPE_ARIA for the driver build from its value
from the core build, as is done for other key types. This had not been done
correctly when adding ARIA support to the PSA subsystem.
