parse_attribute_value_hex_der_encoded: clean up length validation
...
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.

Rewrite parse_attribute_value_hex_der_encoded()
...
Rename the function from parse_attribute_value_der_encoded: the hex aspect
seems important.
There was a buffer overflow due to not validating that the intermediate data
fit in the stack buffer. The rewrite doesn't use this buffer, and takes care
not to overflow the buffer that it does use.
Document all that's going on.
