In order to bring consistency in-tree, migrate all arch code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

Cleanup and preparation commit for linker script generator.
Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.
The symbols _image_rom_start and _image_rom_end corresponds to the group
ROMABLE_REGION defined in the ld linker scripts.
The symbols _image_rodata_start and _image_rodata_end is not placed as
independent group but covers common-rom.ld, thread-local-storage.ld,
kobject-rom.ld and snippets-rodata.ld.
This commit align those names and prepares for generation of groups in
linker scripts.
The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end -> __rom_region_end
The rodata will also use the group symbol notation as:
_image_rodata_start -> __rodata_region_start
_image_rodata_end -> __rodata_region_end

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.

The linker script was missing symbols that defined the boundaries
of kernel memory segments (_image_rom_end, etc.). These are added
so that core/memmap.c can properly account for those segments.

x86 has more complex memory maps than most Zephyr targets. A mechanism
is introduced here to manage such a map, and some methods are provided
to populate it (e.g., Multiboot).
The x86_info tool is extended to display memory map data.
