linker: align _image_text_start/end/size linker symbols name

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_text_start and _image_text_end sometimes includes
linker/kobject-text.ld. This mean there must be both the regular
__text_start and __text_end symbols for the pure text section, as well
as <group>_start and <group>_end symbols.

The symbols describing the text region which covers more than just the
text section itself will thus be changed to:
_image_text_start -> __text_region_start
_image_text_end   -> __text_region_end
