[tint][constant] Add constant::Manager

Constructs deduplicated constants, similarly to type::Manager

The constant::Manager owns the type::Manager so they can be
std::move()'d together without having to risk having the
constant::Manager hold a stale pointer to a moved type::Manager.

Not currently used. That comes next.

Also un-inline type::Manager scalar helpers. Reduces transitive
includes.
