double click doesn't work in devtools protocol

[mgrybyk]

Environment (please complete the following information):

• WebdriverIO version: 6.5.0
• Automation Protocol devtools

Config of WebdriverIO
automationProtocol: "devtools"

Describe the bug
double click doesn't work as expected with devtools implementation of performActions

To Reproduce

browser.url("http://demo.guru99.com/test/simple_context_menu.html");
let elem = browser.$("//button[text()='Double-Click Me To See Alert']");
elem.waitForClickable({ timeout: 2000 });
elem.doubleClick();
browser.pause(5000);

alert should appear in case of successful doubleclick

Expected behavior
double click should be treated as double click not just to separate clicks

Additional context
performActions works as expected, it clicks two times in a row on the element. I think it's an issue with how Puppeteer sends click events with synthetic MouseEvent.

I have a suggestion on how to fix doubleclick.

1. adopt elementClick to accept options
2. create doubleClick command that would trigger elementClick and pass { clickCount : 2 }
3. call devtools doubleClick command in webdriverio doubleClick command if automation protocol is devtools

Sounds like a plan, thanks @mgrybyk !
