[nrfconnect] Disable SHA512 to save flash

[Damian-Nordic]

Problem

I noticed SHA-512 is by default compiled when building nRF Connect firmware although it is not required by Matter nor Thread.

Change overview

Disable SHA-512 to save some flash.

Testing

CI should catch missing function definitions, but also did smoke tests to verify the commissioning still works after this change.
