shim: move |TestState| and |TestConfig| to their own files.
This makes |TestState| and |TestConfig| accessible outside
bssl_shim.cc, as well as the functions SetupCtx() and NewSSL(), which
become methods on |TestConfig|. A whole mess of callbacks move in
order to support this change.
Along the way, some bits of global state are moved (e.g. the global
test clock) and made self-initializing.
This helps with creating a separate binary to perform split
handshakes.
