QUIC: avoid using C99 designated initializers.

They are not supported by MSVC till 2012.

SSL_QUIC_METHOD initialization is moved to run-time to preserve portability
among SSL library implementations, which allows to reduce its visibility.
Note using of a static storage to keep SSL_set_quic_method() reference valid.
