Edward O'Callaghan f31bb81de1 layout: Hoist get_region_range() into libflashrom API
While using the libflashrom API to read specific regions
there is no currently no general way to find the offset
into the read buffer of the expected region.

flashrom_layout_include_region() probably should have
returned the region offset and size if it was included.
However to avoid a change in API signature we can instead
hoist up get_region_range() into the API to be called after.

BUG=b:207808292
TEST=`make` && tested in porting cbfstool use-case.
