Move back the digest update just after
the call to mbedtls_ssl_read_record().
It fits well here as we explain in the
comment associated to the call to
mbedtls_ssl_read_record() that we
update it manually.

The recursion tests for the crypto code
are run in a TF-PSA-Crypto component.
No need to run them in an Mbed TLS
component as well.

Define `_POSIX_C_SOURCE` and `_XOPEN_SOURCE` in a single place that
applies everywhere, to make things simple.
This may break some platforms that require special handling for POSIX
functions and types. Subsequent commits will add platform-specific hacks
as needed.

We were using slightly different guards to decide whether to include
`<unistd.h>` in different places. Unify those.

On MingW, temporarily force the use of the standard versions of `snprintf()`
and `vsnprintf()` (since we set `__USE_MINGW_ANSI_STDIO` in
`mbedtls_platform_requirements.h`). Do not honor `platform.h` configuration,
because with the current TF-PSA-Crypto, `MBEDTLS_PLATFORM_VSNPRINTF_ALT and
`MBEDTLS_PLATFORM_SNPRINTF_ALT` are always enabled on MinGW, so what matters
is the setting of `__USE_MINGW_ANSI_STDIO` when `platform.c` is built, and
until https://github.com/Mbed-TLS/TF-PSA-Crypto/pull/694, the legacy printf
functions are used there.
Revert this commit once the `tf-psa-crypto` module is updated with the merge
of https://github.com/Mbed-TLS/TF-PSA-Crypto/pull/694.

Since Mbed TLS 3.6.0, all officially supported versions of Visual Studio
a printf function family that is sufficiently compliant to C99 for our
purposes, in particular supporting `%zu` for `size_t`. The only platform
without `%zu` that we semi-officially support is older versions of MinGW,
still used in our CI. MinGW provides either a Windows legacy printf or a
standards-compliant printf depending on the value of
`__USE_MINGW_ANSI_STDIO` when compiling each C file. Force the use of the
compliant version. Don't rely on `MBEDTLS_PRINTF_SIZET`, which is defined in
`<mbedtls/debug.h>` and no longer considers the Windows legacy version in
Mbed TLS >= 4.1.

Always activate `__USE_MINGW_ANSI_STDIO` unless overridden on the command
line. This is necessary with older versions of MingW and/or Windows,
where snprintf does not always zero-terminate the buffer, and does
not support formats such as `"%zu"` for size_t and `"%lld"` for long long.
Simplify debug.h accordingly. The macros `MBEDTLS_PRINTF_SIZET`,
`MBEDTLS_PRINTF_SIZET_HAX` and `MBEDTLS_PRINTF_LONGLONG` are no longer
needed, but they are still used in our code base and must stay in debug.h
for backward compatibility.
