Support the WIN64/EFI64 calling convention on all X86_64 platforms

Browse Source 
Add a new calling convention FFI_EFI64, alias FFI_WIN64, on all X86_64
platforms.  This allows libffi compiled on a 64-bit x86 platform to call
EFI functions.

Compile in ffiw64.c and win64.S on all X86_64 platforms.  When compiled
for a platform other than X86_WIN64, ffiw64.c suffixes its functions
with _efi64, to avoid conflict with the platform's actual
implementations of those functions.
