The call wrappers are no longer needed now that GCC can generate
function calls using MS calling convention, so let's get rid of them.

Previously we misaligned stack by 8 in startup.S and compensated
for it in callwrap.S. According to ABI docs (EFI and sysv amd64)
right behaviour is to align stack in startup.S and keep it aligned
in callwrap.S. startup.S part was committed few commits before. This
takes care of callwrap.S.

16-byte boundary, as required by the x86-64 ABI, before calling
grub_main. In some cases, GCC emits code that assumes this
alignment, which crashes if not aligned. The EFI firmware is also
entitled to assume that stack alignment without checking.
