Inspect possibility to remove lifetimes from `Remote` and `Querier`

[jawoznia]

          Can we use `&'static dyn` here instead of adding a new lifetime to the structure? Let's consider removing the reference in the implementation of Querier for dyn Trait as well.

I think that we could port https://github.com/CosmWasm/sylvia/pull/367#discussion_r1595321827 to the main branch to solve this issue
