dundargoc f936a962d0 build: create separate targets for nvim with and without runtime files
This distinction is important for correct dependency management, as the
nvim binary is used to create some runtime files. The nvim binary (and
the target to build it) is thus called `nvim_bin` and the target to
build all of nvim (binary+runtime) is called `nvim`.
