Base+LibTLS: Update CA Certificates list with actual certificates

Browse source 
The CA certificates list now contains the actual certificate data for
approximatly a hundred certificate authorities. These certificates were
generated from https://mkcert.org, which uses the Mozilla CA certificate
list.

This also updates the code for reading the CA certificates.
