These tests are about EC curves/groups, not DH ones, so the description
should be updated accordingly.

This is the backport of commit b8ef2a4455 from the "development" branch
which adapts handshake_fragmentation() to use ECDHE-RSA instead of
DHE-RSA. However, since DHE-RSA is not removed in the mbedtls-3.6 branch,
here tests are added instead of replaced.

PR #9916 adapt some DHE-RSA tests to use ECDHE-RSA instead. However,
since DHE-RSA is not deprecated in mbedtls-3.6 branch, this commit adds
these new tests alongside DHE-RSA ones intead of replacing them in order
to increase test coverage.

We should not manually set the TLS version, the tests are supposed to
pass in 1.3-only builds as well. Instead do the normal thing of setting
defaults. This doesn't interfere with the rest of the testing, so I'm
not sure why we were not doing it.

The test is supposed to be an opaque key test but the
testing function does not support specifying an
opaque driver.

In particular, if interruptible ECDSA is supported but not the deterministic
variant, detect this in psa_sign_hash_start(), whereas before start() would
succeed and psa_sign_hash_complete() would fail. This avoids an
inconsistency between psa_sign_hash() and psa_sign_hash_start() that would
be annoying to handle in test_suite_psa_crypto_op_fail.

ECDSA has two variants: deterministic (PSA_ALG_DETERMINISTIC_ECDSA) and
randomized (PSA_ALG_ECDSA). The two variants are different for signature but
identical for verification. Mbed TLS accepts either variant as the algorithm
parameter for verification even when only the other variant is supported,
so we need to handle this as a special case when generating not-supported
test cases.
In this commit:
* Add manually written not-supported test cases for the signature
operation when exactly one variant is supported.
* Add manually written positive test cases for the verification
operation when exactly one variant is supported.
* Register that !ECDSA but DETERMINISTIC_ECDSA is not tested yet
(https://github.com/Mbed-TLS/mbedtls/issues/9592).
A commit in the framework will take care of automatically generated test cases.

Following "PSA sign/verify: more uniform error on an unsupported hash", some
error cases are detected earlier, so there is some sloppiness in test case
dependencies that is not longer acceptable.
* In test_suite_psa_crypto, one test case for a hash+sign algorithm now
returns NOT_SUPPORTED rather than INVALID_ARGUMENT when the hash is not
supported and the key is invalid.
* In test_suite_psa_crypto_se_driver_hal_mocks, some test cases now error
out before reaching the mocks rather than after when they attempt to
use an unsupported hash.

Allow imports of an ECC public key on an unsupported curve to return
INVALID_ARGUMENT rather than NOT_SUPPORTED. This can happen in our library
code in edge cases when only certain curve families are supported, and it's
acceptable.
The new code does not trigger yet, but it will be useful for a future commit
"Do run not-supported test cases on not-implemented mechanisms"
(forward port of 995d7d4c15406b0a115cadf3f5ec69becafdf20f).

This commit fixes an issue in the GCM shared buffer test case where
input data could be of length 0 and an adequate buffer was not
allocated.

This commit adds test cases for input and output buffer overlap. The
data for the test cases is a duplicate of existing encrypt/decrypt test
cases.
The two test functions gcm_<encrypt/decrypt>_input_output_buffer_overlap
are modified to use a single malloc buffer rounded to the nearest
128-bits/16-bytes for input and output.

This fixes accesses to uninitialized memory in test code if
`psa_crypto_init()` fails.
A lot of those were pointed out by Coverity. I quickly reviewed all calls to
`MD_PSA_INIT()` manually, rather than follow any particular list.

Cleanly reject bits == 0 when calling mbedtls_ecdsa_raw_to_der() and
mbedtls_ecdsa_der_to_raw(). This can plausibly happen when bits is
user-provided data that the calling application doesn't check.
Before this patch, there was typically-benign undefined behavior, such as
adding 0 to a null pointer or calling memcpy on a null pointer with a size
of 0.

Use TEST_CALLOC instead of a fixed-size buffer, so that Asan/Valgrind builds
will detect a buffer overflow.

Instead of skipping some tests when !MBEDTLS_PSA_STATIC_KEY_SLOTS,
add a proper check in the depends_on to verify if
MBEDTLS_PSA_KEY_BUFFER_MAX_SIZE is actually large enough to contain

- MBEDTLS_TEST_STATIC_KEY_SLOTS_SUPPORT_RSA_[2048/4096] are always
defined because they are only used in test_suite_psa_crypto
tests.
- MBEDTLS_TEST_ALLOW_RSA_4096 was renamed as
MBEDTLS_TEST_PK_ALLOW_RSA_KEY_PAIR_4096 because this is only used in
PK related test suites.
