[lmi] access to mc_enum type information [patch 3/3]

[Vaclav Slavik]

[PATCH 3/3] Specialize reconstitutor<> for mc_enum_base. Avoid duplicated code.

Provide reconstitutor<mc_enum_base,Input> specialization for using
try_member_cast<> to cast any_member<> to mc_enum_base.
Do this by calling more specialized reconstitutors (mc_enum_base and
datum_sequence> from reconstitutor<datum_base> in order to
avoid code duplication.
