WIP: Fixed #2242 | AutoComplete - Support optionLabel taking callback

[kyjus25]

Defect Fixes

Fixes #2242

Summary

The docs described being able to pass a callback for when the user wants the label to be a concatenation of multiple fields in the option object but the component was not actually capable of doing so.

Additionally, the field property is deprecated, so the docs have been updated to use optionLabel instead.

Example

<p-autoComplete [optionLabel]="optionLabel" [suggestions]="filteredCountries" (completeMethod)="filterCountry($event)"  />

...
public optionLabel = (option: Country): string => {
  return `${option.label} is a cool country`;
}

Feature Requests

Due to company policy, we are unable to accept feature request PRs with significant changes as such cases has to be implemented by our team following our own processes.
Smaller scaled feature implementations such as adding a property to a component will be considered for merging.

Hi @kyjus25,

Could you please update your PR. Some files have been changed. Also if we implementing this one to the autocomplete, we also need to do the same for dropdown, multiselect, cascadeselect, selectButton, listbox.
