Marc Hartmayer 5340d11165 pv: test_utils: Add TEST-RAND generator for testing ...

Implement a test random number generator (RNG) using the TEST-RAND [1]
generator provided by OpenSSL. This allows writing tests for OpenSSL
functionality where OpenSSL internally uses RNGs, e.g. used for ML-KEM.

The implementation uses RAND_set0_public [2] to set the
thread-local RNG, which requires OpenSSL >= 3.1.
