When USE_PSA_INIT() failed because lack of seedfile, mbedtls_x509write_csr_free()
crashed when called on an unitialized mbedtls_x509write_csr struct.
This moves mbedtls_x509write_csr_init before calling USE_PSA_INIT(),
which could probably fail, and uses the same flow in x509_csr_check()
and x509_csr_check_opaque().

Test data which is compared as a hex string now uses upper case to
match output of mbedtls_mpi_write_string() output. This removes usage
of strcasecmp().

Cases where radix was explictly declared are removed in most cases,
replaced using script. bignum arguments are represented as hexadecimal
strings. This reduces clutter in test data and makes bit patterns
clearer.

In asn1_write tests, when there's a parsing function corresponding to the
write function, call it and check that it can parse what we wrote.

Test with the output buffer size up to *and including* the expected output
size plus one. `... < expected->len + 1` was evidently a mistake.

mbedtls_asn1_write_mpi() correctly handles the sign bit, so there's no
reason not to test that it's handled correctly.
Fix copypasta in test data that was commented out.

Fix a null pointer dereference when performing some operations on zero
represented with 0 limbs: mbedtls_mpi_mod_int() dividing by 2, or
mbedtls_mpi_write_string() in base 2.

Use escape mechanism defined in RFC 1779 when parsing commas and other
special characters in X509 DN values. Resolves failures when generating
a certificate with a CSR containing a comma in subject value.

Systematically replace "TEST_ASSERT( $x <= $y )" by "TEST_LE_U( $x, $y )" in
test_suite_psa_crypto. In this file, all occurrences of this pattern are
size_t so unsigned.

We want to check:
1. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE (the output fits
if the caller uses the key-specific buffer size macro)
2. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE (the output fits
if the caller uses the generic buffer size macro)
3. PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE
(consistency in the calculation)
We were only testing (1) and (2). Test (3) as well. (1) and (3) together
imply (2) so there's no need to test (2).
