Encourage the use of initializing formal parameters

[bwilkerson]

Similar to the use_super_parameters rule, there could be a rule to encourage the use of an initializing formal parameter when the parameter is assigned, unmodified, to a field with the same name as the parameter. For example:

class C {
  int field;

  C({required int field}) : field = field; // Should use 'this.field'.
}

There is prefer_initializing_formals

Sad that I couldn't find it when looking to see whether we had such support.

Honestly, it is difficult to see which lint does what.

I am not sure if having "categories" or hierarchy of them would help. Also, having similar lints or search by synonyms/filter could add a value.

Another suggestion is to have a table of all lints with their bad example.

@sfshaza2 As another data point for the need to make it easier to find relevant lints.
