refactor(bl31): introduce vendor extend rodata section

The purpose of including vendor extend plat.ld.rodata.inc
linker script is for compactly collecting vendor rodata in
intrinsic rodata section.
If vendors define a standalone section and assign the section
placed after __RW_END__, the raw bindry(bl31.bin) will include
bss section with zero value and increase binary size.
