Move std-lib StorageKey tests to in-language tests (#6363)

## Description

Tests in the std-lib were moved to the in-language test programs. The
following additional tests were also added:

- Added tests for `slot()`
- Added tests for `field_id()`
- Added tests for `offset()`
- Added tests for `zero()`
- Added tests for `is_zero()`

## Checklist

- [x] I have commented my code, particularly in hard-to-understand
areas.
- [x] I have updated the documentation where relevant (API docs, the
reference, and the Sway book).
- [ ] If my change requires substantial documentation changes, I have
[requested support from the DevRel
team](https://github.com/FuelLabs/devrel-requests/issues/new/choose)
- [x] I have added tests that prove my fix is effective or that my
feature works.
- [x] I have added (or requested a maintainer to add) the necessary
`Breaking*` or `New Feature` labels where relevant.
