[efi] Split out autoexec script portions of efi_autoboot.c

Browse Source 
The "autoboot device" and "autoexec script" functionalities in
efi_autoboot.c are unrelated except in that they both need to be
invoked by efiprefix.c before device drivers are loaded.

Split out the autoexec script portions to a separate file to avoid
potential confusion.
