734e52899a cmake: linker: arm: utilize zephyr_linker_group(... SYMBOL SECTION)
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.

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

c2842c388d cmake: linker: arm: adding Zephyr CMake linker files for arm arch
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
