This commit removes the API
```
mbedtls_ssl_conf_ciphersuites_for_version()
```
which allows to configure lists of acceptable ciphersuites
for each supported version of SSL/TLS: SSL3, TLS 1.{0,1,2}.
With Mbed TLS 3.0, support for SSL3, TLS 1.0 and TLS 1.1
is dropped. Moreover, upcoming TLS 1.3 support has a different
notion of cipher suite and will require a different API.
This means that it's only for TLS 1.2 that we require
a ciphersuite configuration API, and
```
mbedtls_ssl_conf_ciphersuites()
```
can be used for that. The version-specific ciphersuite
configuration API `mbedtls_ssl_conf_ciphersuites_for_version()`,
in turn, is no longer needed.

Conflicts:
* configs/config-psa-crypto.h: modified here, removed in development
* tests/suites/test_suite_x509parse.data: all conflicts are in depends_on
lines where development made a change unrelated to MBEDTLS_SHAxxx and our
branch either changed `MBEDTLS_SHA256_C` to `MBEDTLS_SHA224_C` or
`MBEDTLS_SHA512_C:!MBEDTLS_SHA512_NO_SHA384` to ``MBEDTLS_SHA384_C`, with
no change to what the test does. Pick the other branch's dependency
changes then apply our SHA dpeendency change.
Remove a kludge to avoid a warning in GCC 11 when calling
mbedtls_sha512_finish_ret with a 48-byte output buffer. This is correct
since we're calculating SHA-384. When mbedtls_sha512_finish_ret's output
parameter was declared as a 64-byte array, GCC 11 -Wstringop-overflow
emitted a well-meaning, but inaccurate buffer overflow warning, which we
tried to work around (successfully with beta releases but unsuccessfully
with GCC 11.1.0 as released). Now that the output parameter is declared as a
pointer, no workaround is necessary.

The server-side `Certificate` handshake message writer checks
whether a certificate is present, and if not fails with:
```
MBEDTLS_ERR_SSL_CERTIFICATE_REQUIRED
```
This should never happen, since the library checks the presence
of a suitable certificate before picking a ciphersuite. It is
therefore more suitable to convert this check into an assertion,
and fail with MBEDTLS_ERR_SSL_INTERNAL_ERROR upon failure.

The error code MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH is only
returned from the internal function
```
mbedtls_ssl_set_calc_verify_md()
```
Moreover, at every call-site of this function, it is only
checked whether the return value is 0 or not, while the
exact return value is irrelevant.
The behavior the library is therefore unchanged if we return 1
instead of MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH in
`mbedtls_ssl_set_calc_verify_md()`. This commit makes this change.

This error is used when the output buffer isn't large enough
to hold our own certificate.
In the interest of cleaning up the error space for 3.0, this commit
removes MBEDTLS_ERR_SSL_CERTIFICATE_TOO_LARGE and replaces its single
use by MBEDTLS_ERR_SSL_BUFFER_TOO_SMALL.

Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.
check_config is the only module which enforces that SHA512 is
enabled together with SHA384.

MinGW and older windows compilers cannot cope with %zu or %lld (there is
a workaround for MinGW, but it involves linking more code, there is no
workaround for Windows compilers prior to 2013). Attempt to work around
this by defining printf specifiers for size_t per platform for the
compilers that cannot use the C99 specifiers.

Fixes for printf format specifiers, where they have been flagged as
invalid sizes by coverity, and new build flags to enable catching these
errors when building using CMake. Note that this patch uses %zu, which
requires C99 or later.

Simple find and replace using `#include (<|")mbedtls/(.*)_internal.h(>|")`
and `#include $1$2_internal.h$3`.
Also re-generated visualc files by running
`scripts/generate_visualc_files.pl`.

`finish_sha384_t` was made more generic by using `unsigned char*`
instead of `unsigned char[48]` as the second parameter.
This change tries to make the function casting more robust against
future improvements of gcc analysis.
