[core] Feature: add generation of missing functions with annotation processing

[serpro69]

Example:

Add some new parameter to a dictionary's category:

    name #this exists in name.yml for example
      strange_name: ["Some gibberish", "More gibberish"]

Annotation processor should generate the following code:

#NameExt.kt

val Name.strangeName = resolve { fakerService.resolve(it, "strange_name") }

After compiling should be possible to call:

Faker().name.strangeName() // => "Some gibberish"

This would particularly be useful if we want to add some extra category parameters without modifying the codebase
