Raise a warning when package doesn't reflect file path

[kpodsiad]

Is your feature request related to a problem? Please describe.

It is a good practice that package should correspond to the file path (or the other way around). Metals could show a warning when it doesn't.

Ideally, this warning should be easy to turn off because it might be annoying if one's working in the workspace when package and paths don't match.

It would be really nice to include that as a Scalafix linting rule 🤔

Should be fairly simple to do that and can be configured by users themselves in the config file. Otherwise we risk the settings growing too much

Embedded in Metals or a standalone one?

I would say embedded in Metals since it would otherwise need a BSP integration for each server.
