x86: efi: Refactor the directory of EFI app and payload support
At present the EFI application and payload support codes in the x86
directory is distributed in a hybrid way. For example, the Kconfig
options for both app and payload are in arch/x86/lib/efi/Kconfig,
but the source codes in the same directory get built only for
CONFIG_EFI_STUB.
This refactors the codes by consolidating all the EFI support codes
into arch/x86/cpu/efi, just like other x86 targets.

Increse it if the default size does not fit the board's needs.
This is most likely due to a large ACPI DSDT table is used.
