refactor(browser): Remove protractor.wrapDriver()

This is a **breaking change**.

Before:
Users could create their own selenium driver instance and enable Protractor on
it like so:
```js
let capabilities = webdriver.Capabilities.chrome();
let driver = new webdriver.Builder().usingServer(seleniumAddress)
    .withCapabilities(capabilities).build();
let browser = protractor.wrapDriver(driver);
```

Over the years, wrapDriver() has become increasingly broken as Protractor
needs extra configuration options that wrapDriver() doesn't set.

After:
This method is removed. If users need a new browser instance, they can
use `browser.forkNewDriverInstance()`.
