include/efi: Override EFIAPI macro for x86_64
This commit overrides the EFIAPI macro definition when using FSP on
x86_64 to ensure the correct calling convention is used.
On i386, there is no side-effect since the C calling convention used
by coreboot and FSP are the same. However, on x86_64, FSP/UEFI uses
the Microsoft x64 calling convention while coreboot uses the System
V AMD64 ABI.
This change resolves this incompatibility by setting EFIAPI to
attribute((ms_abi)) on x86_64 when using FSP.
TEST=Able to build google/rex0 in 32-bit and 64-bit mode.
