[CompTime] Replace partial methods with more flexible interface ICompileTimeContainer

[dadhi]

interface ICompileTimeContainer
{
    bool IsRegistered(Type t);
    bool TryResolve(Type t, out object service);
    IEnumerable<object> ResolveMany(Type t);
}

It may work together with #495

It maybe set or replaced via Container.Rules.

It is flexible as we can implement the same interface both with t4 or source generator.

We may pack t4 together with DryIoc.dll instead of source code only.

The interface may be used for other things, e.g. implement Pure DI by hand (he) or by other container (hehe).
