There are two set of code supporting x86_64: x86_64 using x32 ABI,
and x86 long mode, and this consolidates both into one x86_64
architecture and SoC supporting truly 64-bit mode.
() Removes the x86_64:x32 architecture and SoC, and replaces
them with the existing x86 long mode arch and SoC.
() Replace qemu_x86_64 with qemu_x86_long as qemu_x86_64.
() Updates samples and tests to remove reference to
qemu_x86_long.
() Renames CONFIG_X86_LONGMODE to CONFIG_X86_64.

This file is currently IA32-specific, so it is moved and the
reference to it at the arch-independent layer is moved.

Split out the arch specific syscall code to reduce include pollution
from other arch related headers. For example on ARM its possible to get
errno.h included via SoC specific headers. Which created an interesting
compile issue because of the order of syscall & errno/errno syscall
inclusion.
