LibWeb: Use the global object to access the performance object

Browse source 
Previously, we were accessing the performance through the current
window object. Thus caused a crash when `animate()` was called on an
element within a document with no associated window object. The global
object is now used to access the performance object in places where
a window object is not guaranteed to exist.
