Dictionaries are not ordered in Python 3.5 and before, so building twice
${ZEPHYR_BASE}/samples/application_development/code_relocation/
in a row could lead to a different sections order, different
build/zephyr/include/generated/linker_relocate.d and code_relocation.c
and different binaries.
Fix with a minor change to three "for" loops in the output functions:
make them iterate on sorted(list of sections) instead of the raw and
randomly ordered dictionaries of sections.

Found a few annoying typos and figured I better run script and
fix anything it can find, here are the results...

on non-XIP system, SRAM is the default region, and relocated .data
section and .bss section of SRAM shouldn't be inserted between
_image_rom_start and _image_rom_end, because the memory region between
_image_rom_start and _image_rom_end will construct the mpu ro region.
Also for the newly added memory region on non-XIP system, the
relocated .text secition and .rodata section should also be mpu aligned.
Fixes: #16090.

Discovered with pylint3.
Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.
Python tip:
for i in range(n):
some_list.append(0)
can be replaced with
some_list += n*[0]
Similarly, 3*'\t' gives '\t\t\t'.
(Relevant here because pylint flagged the loop index as unused.)
To do integer division in Python 3, use // instead of /.

(OPTIONAL) was a vestiage from the initial import of the Zephyr code
base and we dont utilize it with the GNU linker. Additionally, the way
(OPTIONAL) gets defined to nothing creates a linker script that lld
(from llvm) doesn't like.

This seems to solve the issue with GH-12033. There seems to be
some compiler optimization that was causing this issue. This
occurs only when the build is re-run by invoking cmake without
clearing the previous build.

This script will relocate .text .data and .bss sections from
required files and places it in the required memory region. This
memory region and file are given to this python script in the form
of a string. Refer to the script for the format of this string and
the procedure to invoke it.
The main goal of this script is to provide a robust way to re-order
the memory contents without actually having to modify the code
(C source code and the linker code).
In simple terms this script will do the job of
__attribute__((section("name"))) for a bunch of files together.
