llext: consistently use "regions" for memory areas
The term "section" has a very specific meaning in the ELF file format.
After 709b2e4 ("llext: automatically merge sections by type"), some of
the code that was originally dealing with ELF sections is now handling
"memory regions" made of multiple ELF sections of the same type.
Make sure to use the term "region" consistently in the code and
log messages to avoid confusion with the original ELF sections.
Notable exception to this is the "ldr->sect" array, which is actively
used outside Zephyr and will need to be phased out in the future.
