feat(`config`): config flag to disallow use of libraries with public methods

### Component

Forge

### Describe the feature you would like

Linked libraries are often not desirable, but often sneak in by accidentally making a single function in the library `public` instead of `internal`. This can cause issues that are hard to track down, such as unexpected contract deploys or [edge case bugs](https://github.com/foundry-rs/foundry/issues/8639), etc). It would be nice to have a flag like `enable_linked_libraries = false` that can be set in `foundry.toml`, that causes a failure during build if any contracts make use of linked libraries
