This commit adds the 8042 scancodes to the shared objects library saving 504 bytes from the RW image. To enable the space savings, define CONFIG_SHAREDLIB in the target's board.h file. BUG=none BRANCH=none TEST=make -j buildall tests TEST=Built samus EC image and verified keyboard still worked in RO and RW. TEST=Built samus EC image with CONFIG_SHAREDLIB enabled and verified that the keyboard still worked in RO and RW. TEST=Enabled CONFIG_SHAREDLIB for glados and cyan and watched build fail.
