Introduce helper functions to free X.509 names and sequences

`mbedtls_x509_name` and `mbedtls_x509_sequence` are dynamically allocated
linked lists that need a loop to free properly. Introduce a static helper
function to do that and use it in `mbedtls_x509_crt_free()`, where the
CRT's issuer and subject names (of type `mbedtls_x509_name`) and the
SubjectAlternativeName and ExtendedKeyUsage extensions (of type
`mbedtls_x509_sequence`) need freeing. Increases code-clarity and saves
a few bytes of flash.
