This patch replaces similiarly structured test functions
for:

* MBEDTLS_ECP_DP_SECP192R1

* MBEDTLS_ECP_DP_SECP256R1
* MBEDTLS_ECP_DP_SECP384R1
* MBEDTLS_ECP_DP_BP512R1R1

with a more generic version, which adjusts the parameters, based on the `curve_id` field,
provided by the testing data.

The python test framework has been updated to provide that extra field.

f287366376 Simplify logic and document test_cases_for_values 
Explain what's going on in BignumModRawConvertRep.test_case_for_values.

Simplify the logic and the interdependencies related to limb sizes:
* Montgomery is the special case, so base the decisions on it.
* As soon as we've encountered one limb size, no matter what it is,
  give up.

No behavior change, other than changing the numbering of test cases (which
previously included more skipped test cases).

ad335b55ff Fix representation conversion with 32-bit limbs 
The Montgomery representation depends on the limb size. So the
representation conversion test cases need separate 64-bit and 32-bit cases
when the representation is Montgomery.
