Add support to ANSI OSC52

Add support to ANSI OSC52 sequence to manipulate selection and clipboard
data. The sequence specs supports multiple clipboard selections but we
only support the common ones, system and primary clipboard selections.

This adds a new event listener to the common terminal module
`onClipboard` to allow external implementations to hook into it.

The addon uses the browser Clipboard API to read/write from and to the
clipboard. The default `ClipboardProvider` uses the browser Clipboard
API. This means it only supports read/write to and from the system
clipboard.

## xterm-addon-clipboard
An addon for [xterm.js](https://github.com/xtermjs/xterm.js) that enables accessing the system clipboard. This addon requires xterm.js v4+.
### Install
```bash
npm install --save xterm-addon-clipboard
```
### Usage
```ts
import { Terminal } from 'xterm';
import { ClipboardAddon } from 'xterm-addon-clipboard';
const terminal = new Terminal();
const clipboardAddon = new ClipboardAddon();
terminal.loadAddon(clipboardAddon);
```
To use a custom clipboard provider
```ts
import { Terminal, IClipboardProvider, ClipboardSelection } from 'xterm';
import { ClipboardAddon } from 'xterm-addon-clipboard';
function b64Encode(data: string): string {
// Base64 encode impl
}
function b64Decode(data: string): string {
// Base64 decode impl
}
class MyCustomClipboardProvider implements IClipboardProvider {
private _data: string
public readText(selection: ClipboardSelection): Promise<string> {
return Promise.resolve(b64Encode(this._data));
}
public writeText(selection: ClipboardSelection, data: string): Promise<void> {
this._data = b64Decode(data);
return Promise.resolve();
}
}
const terminal = new Terminal();
const clipboardAddon = new ClipboardAddon(new MyCustomClipboardProvider());
terminal.loadAddon(clipboardAddon);
```
See the full [API](https://github.com/xtermjs/xterm.js/blob/master/addons/xterm-addon-clipboard/typings/xterm-addon-clipboard.d.ts) for more advanced usage.
