[api] add touchScreen.tap (#639)

Browse Source 
This patch:
- adds `page.touchscreen` namespace, similar to `page.mouse` and `page.keyboard`.
- adds tapping to multiple layers:
  - `page.touchscreen.tap`
  - `page.tap` - convenience method which accepts selector
  - `elementHandle.tap`

Fixes #568 and #569.
