Same rationale as previous "Rm useless use of MD" commits.
Here the first two test functions were already not depending on MD_C,
but the new version is much simpler, as it avoids having two versions of
the code depending on the value of USE_PSA.

Tests are not here to demonstrate best practice, but to test a specific
part of the code. Using an RNG provided by the test framework also makes
the test code more focused on what we actually mean to test.
This brings the number of tests skipped in test_suite_rsa in
test_psa_crypto_config_accel_hash_use_psa down to 0 (from 50).

We had a message in the data file, and were computing its hash in the
test function. It is more efficient (and simpler when it comes to
dependencies) to directly have the message hash in the data file.
It was probably this way because some test vectors provide the message
for the sake of all-in-one implementation that hash-and-sign at once.
But our API gets a hash as the input and signs it. In unit tests, this
should be reflected in the signature of the test function, which should
take a hash as input.
The changes to the .data file were done using the following python
script:
import hashlib
suite = 'pkcs1_v15'
functions = {
'pkcs1_rsassa_v15_sign': (10, 12),
'pkcs1_rsassa_v15_verify': (6, 8),

The encrypt/decrypt cases don't depend on actually computing a hash,
just on information about it being available, and this information is

Having the whole .function file depend on SHA-1 was wrong: dependencies
in .function files are for compile-time dependencies all functions in
this file build just fine without SHA-1. It's just some tests cases that
do need SHA-1 at runtime, use dependencies on those specific tests in
the .data file then.
This reduces the number of cases skipped in this test suite in
test_psa_crypto_config_accel_hash_use_psa from 28 (all of them) down to
12 (those that actually use SHA-1 as opposed to no hash).

With this commit, test_suite_pk achieves parity between:

- same minus MD (from all.sh's test_crypto_full_no_md)
and between:
- default config plus use_psa minus PKCS#1v2.1
- same with accelerators (test_psa_crypto_config_accel_hash_use_psa)

While at it, also fix buffer size for functions that already depend on
USE_PSA: it should be PSA_HASH_MAX_SIZE for functions that always use
PSA, and the new macro MBEDTLS_USE_PSA_MD_MAX_SIZE for functions that
use it or not depending on USE_PSA.
The only case where MBEDTLS_MD_MAX_SIZE is OK is when the function
always uses MD - currently this is the case with
pk_sign_verify_restart() as it is incompatible with USE_PSA anyway.

When MD is only used to compute a size, use md_internal.h instead.
When it's actually used to compute a hash, mark the test function as
depending on it. This is probably suboptimal in the long run, and we
might want to either adapt the code so that it can use PSA Crypto
instead, or just pre-compute the hash in the test data.
