URL constructor implementation is incomplete

[stefanlucas]

Describe the bug
URL constructor is partially implemented, it only supports one argument and the url parsing is limited. We should move the parsing to UrlLib and use platform specific functions to parse the URL and get the parts.

Expected behavior
Same behavior as the javascript URL constructor

Other

• Platform: Win32, Android, iOS
