The root cause of #38591 was region symbols being placed before the
section description for data region.
To support both schemes with the linker generator, a new
`SYMBOL SECTION` argument has been added to the zephyr_linker_group()
function.
This commit updates the arm/linker.cmake CMake linker file to use the
new `SYMBOL SECTION` argument for the data region group and text region
group so that those two groups now behave identical to the behavior when
using the cortex_m linker.ld template.

This commit add devicetree memory regions added to arm/linker.cmake.
The following memory regions are now added to the generated linker
script and scatter file if they exists in the devicetree.
- chosen: zephyr,itcm
- chosen: zephyr,dtcm
- nodelabel: ti_ccfg_partition
- nodelabel: sram1
- nodelabel: sram2
- nodelabel: sram3
- nodelabel: sram4
- nodelabel: sdram1
- nodelabel: sdram2
- nodelabel: backup_sram
Also support for the itcm and dtcm section and their placement in
corresponding memory regions has been added.

This is the initial version of a Zephyr CMake linker file for the arm
architecture.
This file defines memory regions, groups, linker sections and symbols
for the arm architecture.
It also sources the common common-ram.cmake, common-rom.cmake,
debug-sections,cmake, and thread-local-storage.cmake.
It configure sections for SoC families using zephyr_linker_sources()
functions:
- nxp_imx

Converted existing ld script templates into CMake files.
This commit takes the common-ram.ld, common-rom.ld, debug-sections.ld,
and thread-local-storage.ld and creates corresponding CMake files for
the linker script generator.
The CMake files uses the new Zephyr CMake functions:
- zephyr_linker_section()
- zephyr_linker_section_configure()
- zephyr_linker_section_obj_level()
to generate the same linker result as the existing C preprocessor based
scheme.
