Remove now-native setWindowBounds functionality

[codebytere]

This PR removes the setWindowBounds utility function, as it's natively available in Electron starting with v4.0.0 as a result of this PR.

You also need to update

electron-util/index.js

Line 123 in e7b9fe0

exports.setWindowBounds(bounds, options);

to use the native method.

And

electron-util/index.d.ts

Lines 215 to 237 in e7b9fe0

	export interface SetWindowBoundsOptions {
	/**
	The window to set the bounds of.
	Default: Current window
	*/
	readonly window?: BrowserWindow;
	/**
	Animate the change.
	@default false
	*/
	readonly animated?: boolean;
	}
	/**
	Set the bounds of a window. This is similar to the [`BrowserWindow#setBounds()`](https://electronjs.org/docs/api/browser-window#winsetboundsbounds-animate) method, but it allows setting any of the `x`, `y`, `width`, `height` properties, instead of forcing you to set them all at once.
	The properties that are not set will just fall back to the current ones.
	@param bounds - New window bounds.
