linker: align _image_rodata and _image_rom start/end/size linker symbols

Browse source 
Cleanup and preparation commit for linker script generator.

Zephyr linker scripts provides start and end symbols for each larger
areas in the linker script.

The symbols _image_rom_start and _image_rom_end corresponds to the group
ROMABLE_REGION defined in the ld linker scripts.

The symbols _image_rodata_start and _image_rodata_end is not placed as
independent group but covers common-rom.ld, thread-local-storage.ld,
kobject-rom.ld and snippets-rodata.ld.

This commit align those names and prepares for generation of groups in
linker scripts.

The symbols describing the ROMABLE_REGION will be renamed to:
_image_rom_start -> __rom_region_start
_image_rom_end   -> __rom_region_end

The rodata will also use the group symbol notation as:
_image_rodata_start -> __rodata_region_start
_image_rodata_end   -> __rodata_region_end
