[Stock] Add cleaner stock

[Stock]
fss0={sd path}
stock=1

Can now work for both older and new HOS versions.

- <= 6.2.0 loads nothing and removes kernel patching.
- >= 7.0.0 loads exo, wb and removes kernel patching.

This requires that fss0 {sd path} is valid. Otherwise it will fail on ini cfg parsing.

If <= 6.2.0 and no FSS0
[Stock]
stock=1

will provide a cleaner stock with no kernel patching.

| fullsvcperm=1 | Disables SVC verification (full services permission) |
| debugmode=1 | Enables Debug mode. Obsolete when used with exosphere as secmon. |
| atmosphere=1 | Enables Atmosphère patching |

**Note1**: When using the wildcard (`/*`) with `kip1` you can still use the normal `kip1` after that to load extra signle kips.
