Provide X.509 name comparison based on raw ASN.1 data
This commit provides a new function `mbedtls_x509_name_cmp_raw()`
to x509.c for comparing to X.509 names by traversing the raw ASN.1
data (as opposed to using the dynamically allocated linked list
of `mbedtls_x509_name` structures). It has external linkage because
it will be needed in `x509_crt` and `x509_crl`, but is marked
internal and hence not part of the public API.
