UserStore should use IDbContextFactory<TContext> (instead of just TContext) if available

[springy76]

UserStore<TUser, TRole, TContext, TKey, TUserClaim, TUserRole, TUserLogin, TUserToken, TRoleClaim> just ignores the fact my app is using (Pooled)DbContextFactories.

I don't know if UserStore could auto-detect the presence of IDbContextFactory registration or if 2 similar classes would have to be maintained.

Such thing also should fix issues like #22031
