[PATCH 18/22] [provider] CryptoPkg/openssl: use our own predefined providers

["Gerd Hoffmann" <kraxel@redhat.com>]

Define our own ossl_predefined_providers, so we can easily
compile out some or all of them for testing purposes.

Effect seems to not be that big though:

 1157758 TlsDxe  ('default' + 'base' + 'null')
  897022 TlsDxe  (only 'null')

So not sure yet if we actually want/need this ...
