Add new flag ENABLE_STATIC_CRT for Windows

This change adds the CMake option;

  ENABLE_STATIC_CRT  Build libnghttp2 against the MS LIBCMT[d]

This avoids linking to msvcrt.lib for binaries to compile (/MT[d])
and link against the static C Runtime libcrt.lib, and
avoiding the msvcrt[d].dll dependency.
