These are build-only components so this was never supported for sure.
Let's stick to what's really tested for now, and expand later (with
proper testing!) if there's demand for more flexibility.

These were temporaries to avoid unwanted use of low-level modules. Now
that we have test components with those modules fully disabled (replaced
with drivers), we no longer need these tests - which were out of date
too.

Restore guards from the previous release, instead of the new, more
permissive guards.

I chose to divide along the lines of Weierstrass vs other curve shapes
(currently just Montgomery), mainly because it's the first thing that
came to mind.
It happened to reveal an issue in the logic for when (deterministic)
ECDSA and ECJPAKE are built-in, which this commit is also fixing.

Separate the fits-in-buffer check (*data_length <= data_size) from the
we-think-it's-a-sensible-size check (*data_length <=
MBEDTLS_X509_MAX_DN_NAME_SIZE).
This requires using an intermediate buffer for the DER data, since its
maximum sensible size has to be larger than the maximum sensible size for
the payload, due to the overhead of the ASN.1 tag+length.
Remove test cases focusing on the DER length since the implementation no
longer has a threshold for it.

Fix the expected output in some test cases.
Add a few more test cases to exercise both a payload length around 256 bytes
and a DER length around 256 bytes, since both are placed in a 256-byte
buffer (value of MBEDTLS_X509_MAX_DN_NAME_SIZE).

Due to differing validations amongst X.509 library functions, there are
inputs that mbedtls_x509_string_to_names() accepts, but it produces output
that some library functions can't parse. Accept this for now. Do call the
functions, even when we don't care about their return code: we're ok with
returning errors, but not with e.g. a buffer overflow.

In particular, "X509 String to Names: long hexstring (DER=258 bytes, too long)"
causes a buffer overflow in parse_attribute_value_der_encoded().

Before this PR, the tests passed without this, but they shouldn't have.
Accelerators need to declare what curves they support, and if no curve
is declared as accelerated, the built-in implementations of algs and key
types need to be enabled.

Those components were introduced in #7103, resolving #6622: Some PSA
ECC size macros are too small when the largest accelerated curve is
larger than the largest built-in curve.
At that point, it was not possible yet to omit all built-in curves,
so we made these components that had only one (small) curve built-in and
all the others accelerated.
Now that it's possible to disable all ECC built-ins, and we have tests
doing that, we don't need that kind of fiddling any more.
Note: these component disabled RSA in order to make sure max key size
macros were not taken from RSA. We have test components with all of ECC
accelerated and RSA disabled
(component_test_psa_crypto_config_accel_ecc_no_bignum and
component_test_psa_crypto_config_accel_ecc_ffdh_no_bignum), making the
"all curves except one" components really redundant.
Note: removing them was one of the items in #7757.
