Interoperability checks for OID values

### Description

The OID module defines many OIDs. Mbed TLS tests that it has the correct values indirectly by using parsing those values in X.509 test data and by making TLS connections. With the split of Mbed Crypto and Mbed TLS, there's nothing to verify that we have the correct values for all the OID constants in Mbed Crypto itself. We should add some verification mechanism, e.g. asking some other library to parse our OIDs or checking the value against some online database.

### Issue request type

[ ] Question
[x] Enhancement
[ ] Bug

Start by reading the OID module and the existing indirect checks through X.509 test data and TLS connections, then review related issue #77. Choose a verification mechanism such as another library or an online database, and consider all OID constants covered. Done means the values in Mbed Crypto are independently checked.
