Create Getters Library Once v4-core ossifies

[ewilz]

Component

General design optimization (improving efficiency, cleanliness, or developer experience)

Describe the suggested feature and problem it solves.

We plan to use extsload for most access to v4 PoolManager storage, but while the repo is still being heavily developed, it can be hard to keep up with a such a library. Eventually we need to take any unnecessary getters inside PoolManager and abstract them into a library that utilizes extsload
