This function, like its cousin z_tsc_read(), can be shared between
subarches. Note: it's unclear to me if we actually need these to be
two separate functions (do we need serialization?) or if they can
be combined into one function. Add that to the to-do list.

The previous linker script was barebones and non-standard. It is
replaced with a script conforms to the rest of the Zephyr arches,
utilizing include/linker headers and standard macros.
link-tool-gcc.h is updated to account for the "i386:x86-64" arch and
the generation of 64-bit ELF binaries.

Fleshed out z_arch_esf_t and added code to build this frame when
exceptions occur. Created a separate small stack for exceptions and
shifted the initialization code to use this instead of the IRQ stack.
Moved IRQ stack(s) to irq.c.

The IRQ_OFFLOAD_VECTOR config option is also moved to the arch level,

Using the arch Kconfig here, instead of kernel/Kconfig. Intel64 with
the SysV ABI requires some pretty big stacks. These 4K-8K defaults
are arguably a bit small, but the Zephyr defaults are REALLY too small.

First "complete" version of Intel64 support for x86. Compilation of
apps for supported boards (read: up_squared) with CONFIG_X86_LONGMODE=y
is now working. Booting, device drivers, interrupts, scheduling, etc.
appear to be functioning properly. Beware that this is ALHPA quality,
not ready for production use, but the port has advanced far enough that
it's time to start working through the test suite and samples, fleshing
out any missing features, and squashing bugs.

This patch adds basic build infrastructure, definitions, a linker
script, etc. to use the Zephyr and 0.10.1 SDK to build a 64-bit
ELF binary suitable for use with GRUB to minimally bootstrap an
Apollo Lake (e.g., UpSquared) board. The resulting binary can hardly
be called a Zephyr kernel as it is lacking most of the glue logic,
but it is a starting point to flesh those out in the x86 tree.
The "kernel" builds with a few harmless warnings, both with GCC from
the Zephyr SDK and with ICC (which is currently being worked on in
a separate branch). These warnings are either related to pointer size
differences (since this is an LP64 build) and/or dummy functions
that will be replaced with working versions shortly.

Commit db48d3e22a ("sys_sem: add build time definition macros")
recently introduced SYS_SEM_DEFINE() and defined it in terms of
Z_DECL_ALIGN() and __in_section() to force the _k_sem linker section.
It is however cleaner and less obscur to use Z_STRUCT_SECTION_ITERABLE()
and list the _sys_sem linker section alongside the _k_sem one.

- Remove unused variables and an unused 'sys' import
- Simplify 'if len(foo) != 0' to 'if foo'. Non-empty lists/dicts/etc.
are truthy in Python.
- Use a raw string to fix this warning:
scripts/footprint/size_report:270:0: W1401: Anomalous backslash
in string: '\.'. String constant might be missing an r prefix.
(anomalous-backslash-in-string)
The issue is that '\.' just happens to work due to not being
recognized as an escape sequence.
Escape sequences are not interpreted in raw strings, so they're safer
for regexes.
- Replace 'is 0' with '== 0'. 'is' is for testing object identity, and
0 isn't guaranteed to be a unique object (but always is in practice).

Convert how we get the various chosen properties like "zephyr,console"
to use the new kconfig functions like dt_chosen_to_label.
Because of how kconfig parses things we define a set of variables of the

macros.
This conversion allows us to remove code in gen_defines.py for the
following chosen properties:
