Merge /u/gmbr3/gnu-efi/ branch CHAR16 into master

https://sourceforge.net/p/gnu-efi/code/merge-requests/48/

Make VOID a typedef

'void' is a type so VOID can be typedef instead of
a '#define' to improve compiler output

Make WCHAR and CHAR16 identical

And actually use wchar_t
gnu-efi already uses L string literals which are of type
wchar_t

Make CHAR8 and similar be defined the same way edk2 does it.

efibind: Fix usage of efi headers from C++ code

* __STDC_VERSION__ is undefined when headers are called from C++
code resulting in not using stdint.h and efibind.h
"making a guess" on what they are. extern "C" will not define
__STDC_VERSION__.
* Always leverage stdint.h on C++.
* Honestly, gnu-efi should always use stdint.h, or find a better
way to detect it. (or platforms without it need to catch up to 2007)

Problem introduced with commit a46a62b12b58139c31d4288384808365c4053bf2
(Fix some types gcc doesn't like).

Avoid this by adding intptr_t (and uintptr_t) typedefs for builds that does
not include stdint.h.

Add EFI_DRIVER_ENTRY_POINT support for MSVC/ARM64

Similar to what we do for other MSVC architectures.

Make sure stdint.h is always used with MSVC on ARM/ARM64, since all
the versions of Visual Studio that support ARM or ARM64 have that
header. Without this, uint64_t would be defined to unsigned long,
which is 32-bits in the Microsoft world.

Also fix aarch64/initplat.c so that memset/memcpy only apply
to gcc. Otherwise MSVC throws an error for __SIZE_TYPE__.

Updating this patch to v2, since it turns out MSVC will also emit
memset and memcpy intrinsics that we can use an implementation for.
This is true for both ARM and ARM64.
To make this work, I'm defining __SIZE_TYPE__ to UINTN if not
already defined.

This adds support for the C99 uintXX_t types when building for
older versions of the standard, like the other architectures
already implement.
