Build: merge build macros between FIP_ and FWU_FIP_
The build system supports generating two FIP images, fip and fwu_fip.
Accordingly, we have similar build macros.
FIP_ADD_PAYLOAD <--> FWU_FIP_ADD_PAYLOAD
CERT_ADD_CMD_OPT <--> FWU_CERT_ADD_CMD_OPT
FIP_ADD_IMG <--> FWU_FIP_ADD_IMG
The duplicated code increases the maintenance burden. Also, the build
rule of BL2U looks clumsy - we want to call MAKE_BL to compile it from
source files, but we want to put it in fwu_fip. We can not do it in a
single macro call since the current MAKE_BL does not support fwu_fip.
To refactor those in a clean way is to support one more argument to
specify the FIP prefix. If it is empty, the images are targeted to
fip, whereas if the argument is "FWU_", targeted to fwu_fip.
The build macros prefixed with FWU_ go away.
