Feat: Enforce custom provider types

[thiagomini]

Description

We want to allow users to prefer one type of custom provider over the others. For instance, factory providers over value providers can significantly increase performance.

Acceptance Criteria

Given the options below:

// ...
rules: {
  '@trilon/enforce-custom-provider-type': [ 
   'warn', {  
     prefer: 'factory'
   }
  ]
}

Then, the following code will be considered Invalid:

const customValueProvider: Provider = {
  provide: 'TOKEN',
  useValue: 'some-value' // ⚠️ provider is not of type "factory"
}

const customClassProvider: Provider = {
  provide: AbstractClass,
  useClass: SomeClass  // ⚠️ provider is not of type "factory"
}

And the following code is considered Valid:

const factoryProvider: Provider = {
  provide: 'TOKEN',
  useFactory: () => 'some-value'
}

@tuxmachine I'm wondering what we could use to determine that an object is a provider, @tuxmachine 🤔 Maybe we should check for the explicit "Provider" type from Nest? Otherwise, I fear this might get some false-positives from other objects that are not providers
