npcx: Build RW_B and support sysjump to it
This patch allows a board to include another RW image in ec.bin.
The size of each copy is a quarter of the flash size on Fizz.
BUG=b:38462249
BRANCH=none
CQ-DEPEND=CL:568297
TEST=Run sysjump RW/A/B. Verify there is no size change by running
make savesizes/newsizes. Run objdump -h build/fizz/ec.obj:
