Support other locator types in ElementFactory

[mialeska]

Currently only XPath locators for multiple elements are supported.
Although some locator types could be converted to XPath:

• By.name("awesome") -> By.xPath("//[@name='awesome']") (please note that this is for web, e.g. for desktop xPath would be //[@name='awesome'] according to https://github.com/microsoft/WinAppDriver/blob/master/Docs/AuthoringTestScripts.md )
• By.id("awesome") -> By.xPath("//*[@id='awesome']")
  and so on
