[Feature]: BC - refactor composables accordingly to VSF new architecture

[Baroshem]

How the project can be improved?

This task is a breaking change on top of a breaking change. In VSF we have introduced a new architecture where we would like to get rid of composables package (with corresponding getters) in favor of theme composables.

As this is a huge breaking change, I would like to plan it for the 1.5 version and prepare community for this upcoming change.
