Fix an issue where updating a `zephyr_code_relocate()` call in CMake
didn't trigger regeneration of `code_relocation.c` and linker scripts.
The generation command was missing a dependency on the aforementioned
input text file, where the outcome of each call is cached.

For applications relocating big parts of the code with many sections,
builds were failing on Windows due to hitting the max command-line
length on that platform.
Fix this by using a file to store the dictionary passed to the python
script.

It's useful for RAMABLE_REGION to have a uniform name when
CODE_DATA_RELOCATION is supported, because otherwise the build system
needs to be aware of how the region name differs between architectures.
Since architectures tend to prefer one of 'SRAM' or 'RAM' for that
region, prefer to use 'RAM' as the more general term.

This implements support for relocating code to chosen memory regions via
the `zephyr_code_relocate` CMake function for RISC-V SoCs. ARM-specific
assumptions that were made by gen_relocate_app.py need to be corrected,
in particular not assuming any particular name for the default RAM
section (which is 'SRAM' for most ARM pltaforms) and not assuming 32-bit
pointers (so the test works on RV64).

Move scripts needed by the build system and not designed to be run
individually or standalone into the build subfolder.

Zeroing the BSS and copying data to RAM with regular memset/memcpy may
cause problems when those functions are assuming a fully initialized
system for their optimizations to work e.g. some instructions require
an active MMU, but turning the MMU on needs the .bss section to be
cleared first, etc.
Commit c5b898743a ("aarch64: Fix alignment fault on z_bss_zero()")
provides a detailed explanation of such a case.
Replacing z_bss_zero() with an architecture specific one is problematic
as the former may see new sections added to it that would be missed by
the later. The same reasoning goes for z_data_copy().
Let's make maintenance much easier by providing weak versions of
memset/memcpy that can be overridden by architecture-specific safe
versions when needed.

Fixes: #28847
This commit fixes two places that was causing gen_relocate_app to fail
in windows.
gen_relocate_app.py now splits only on first `:` in
`<MEM_REGION>:<file>`.
Windows contains `:` in path, thus only first `:` is valid for splitting
mem region and file path.
Second part of the issue is fixed in CMake where `'` was used for
quoting of command arguments.
This causes a file not found on Windows because the final `'` would be
treated as part of the filename. Similar the first `'` would be treated
as path of the mem region name.
This is fixed by using `"` for quoting, which works correctly on all
platforms.

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.

No functional change expected.
This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting non-intrusive porting to other (commercial) toolchains.
