Before `mbedtls_ssl_setup`, config functions should
be called. Without it, `mbedtls_ssl_setup` will raise
invalid value error.

This commit adds four known answer tests for TLS 1.3 record protection
from the following sources:
- RFC 8448 "Example Handshake Traces for TLS 1.3"
- tls13.ulfheim.net "The New Illustrated TLS Connection"
It extends the test coverage of the existing record protection tests
in the following ways:
- The existing record protection tests hand-craft record transform
structures; the new tests use the function
mbedtls_ssl_tls13_populate_transform()
from library source to create an TLS 1.3 transform from raw
key material and connection information.
- The existing record protection tests only check that encryption
and decryption are inverse to each other; as such, they don't
catch non-compliant implementations of encryption and decryption
which happen to be inverse to each other. By adding a known answer
test for TLS 1.3 record protection, can gain confidence that our
implementation is indeed standards-compliant.

Instances of `mbedtls_ssl_session` represent data enabling session resumption.
With the introduction of TLS 1.3, the format of this data changes. We therefore
need TLS-version field as part of `mbedtlsl_ssl_session` which allows distinguish
1.2 and 1.3 sessions.
This commit introduces such a TLS-version field to mbedtls_ssl_session.
The change has a few ramifications:
- Session serialization/deserialization routines need to be adjusted.
This is achieved by adding the TLS-version after the header of
Mbed TLS version+config, and by having the subsequent structure
of the serialized data depend on the value of this field.
The details are described in terms of the RFC 8446 presentation language.
The 1.2 session (de)serialization are moved into static helper functions,
while the top-level session (de)serialization only parses the Mbed TLS
version+config header and the TLS-version field, and dispatches according
to the found version.
This way, it will be easy to add support for TLS 1.3 sessions in the future.
- Tests for session serialization need to be adjusted
- Once we add support for TLS 1.3, with runtime negotiation of 1.2 vs. 1.3,
we will need to have some logic comparing the TLS version of the proposed session
to the negotiated TLS version. For now, however, we only support TLS 1.2,
and no such logic is needed. Instead, we just store the TLS version in the
session structure at the same point when we populate mbedtls_ssl_context.minor_ver.
The change introduces some overlap between `mbedtls_ssl_session.minor_ver` and
`mbedtls_ssl_context.minor_ver`, which should be studied and potentially resolved.
However, with both fields being private and explicitly marked so, this can happen
in a later change.

Previously the check was convoluted. This has been simplified

Call the output size macros specifically with asymmetric keys, which
would cause a crash (and thus test fail) should this fix get regressed.

This file had temporary MBEDTLS_xxx dependencies because it was created when
support for PSA_WANT_xxx was still incomplete. Switch to the PSA_WANT_xxx
dependencies
This fixes the bug that "PSA storage read: AES-GCM+CTR" was never executed
because there was a typo in a dependency.

with the block sizes and will escape the loop when appropriate
The test cases, as pointed out by Gilles, could be harmful in
the future and testing a test case is not generally necessary
