Renderer -> Renderer2 migration

Automatically migrates from Renderer to Renderer2 by changing method calls, renaming imports and renaming types. Tries to either map method calls directly from one renderer to the other, or if that's not possible, inserts custom helper functions at the bottom of the file.

Before

import { Renderer, ElementRef } from '@angular/core';

@Component({})
export class MyComponent {
  constructor(private _renderer: Renderer, private _elementRef: ElementRef) {}

  changeColor() {
    this._renderer.setElementStyle(this._element.nativeElement, 'color', 'purple');
  }
}

After

import { Renderer2, ElementRef } from '@angular/core';

@Component({})
export class MyComponent {
  constructor(private _renderer: Renderer2, private _elementRef: ElementRef) {}

  changeColor() {
    this._renderer.setStyle(this._element.nativeElement, 'color', 'purple');
  }
}
