Routine Description:
  Create a Read to Boot Event.  
  
  Tiano extended the CreateEvent Type enum to add a ready to boot event type. 
  This was bad as Tiano did not own the enum. In UEFI 2.0 CreateEventEx was
  added and now it's possible to not voilate the UEFI specification and use 
  the ready to boot event class defined in UEFI 2.0. This library supports
  the R8.5/EFI 1.10 form and R8.6/UEFI 2.0 form and allows common code to 
  work both ways.

Arguments:
  @param LegacyBootEvent  Returns the EFI event returned from gBS->CreateEvent(Ex)

Return:
  EFI_SUCCESS   - Event was created.
  Other         - Event was not created.
