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

Browse source 
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.
