Refactors material components to regular datums (#94596)

## About The Pull Request
This was LONG overdue and its finally time. Refactors 2 components to
regular datums
- `/datum/component/material_container` -> `/datum/material_container`
- `/datum/component/remote_materials` -> `/datum/remote_materials`

Reduced memory overhead and stops misuse of component i.e. storing it in
a variable

## Changelog
🆑
refactor: refactored material container code to reduce memory overhead.
