Currently CertVerifyProcBuiltin implicitly uses GetGlobalCertNetFetcher() to get the network fetching dependency needed for OCSP/CRL/AIA.

Instead of using a global, the network dependency for the certificate verifier should be explicitly bound to the CertVerifyProcBuiltin - preferably during construction.

Given that the CertVerifier now has a per-profile affinity (https://chromium.googlesource.com/chromium/src/+/3d8e16ca0ca8c9b5f4f7efd797fa58fd958b819d) this should be simpler to fix.
