build(fdt-wrappers): introduce FDT wrappers makefile
This has been introduced to simplify dependencies on the FDT wrappers.
We generally want to avoid pulling in components on a file-by-file
basis, particularly as we are trying to draw conceptual boxes around
components in preparation for transitioning the build system to CMake,
where dependencies are modelled on libraries rather than files.
