Enforce RROs for all the build-time ROs

This CL is to generate every static RRO package for its target package
automatically at build-time.

BOARD_ENFORCE_RRO build variable is added to specify whether enforcing
RRO is required or not.

BOARD_ENFORCE_RRO_EXEMPT_SOURCES build variable is added to specify
the module list of which item should be exempt from enforcing RRO.
