efi: Split out table-listing code into a new file
This code is used with EFI_LOADER but is also useful (with some
modifications) for the EFI app and payload. Move it into a shared
file.
Show the address of the table so it can be examined if needed. Also show
the table name as unknown if necessary. Our list of GUIDs is fairly
small.
