tree: More use accessor functions for struct region fields

Always use the high-level API region_offset() and region_sz()
functions. This excludes the internal `region.c` code as well
as unit tests. FIT payload support was also skipped, as it
seems it never tried to use the API and would need a bigger
overhaul.
