feat(core): add automatic migration from Renderer to Renderer2 (#30936) Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports: * Renaming imports. * Renaming property and method argument types. * Casting to `Renderer`. * Mapping all of the methods from the `Renderer` to `Renderer2`. Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like. Before: ``` class SomeComponent { createAndAddText() { const node = this._renderer.createText(this._element.nativeElement, 'hello'); node.textContent += ' world'; } } ``` After: ``` class SomeComponent { createAndAddText() { const node = __rendererCreateTextHelper(this._renderer, this._element.nativeElement, 'hello'); node.textContent += ' world'; } } function __rendererCreateTextHelper(renderer: any, parent: any, value: any) { const node = renderer.createText(value); if (parent) { renderer.appendChild(parent, node); } return node; } ``` This PR resolves FW-1344.

refactor(core): move renderer2 migration lint rule into google3 folder (#31817) Moves the `renderer_to_renderer2` migration google3 tslint rule into the new `google3` directory. This is done for consistency as we recently moved all google3 migration rules into a new `google3` folder (see: f69e4e6f770907f6811de88e52692df1a3d2f43e). PR Close #31817
