For historical reasons, nir and vtn were compiled together, and a bunch of vtn specific targets were defined in src/compiler/meson.build. Now that we can, make src/compiler/spirv produce an internal library that depends on NIR, and is used by the drivers/tools. Also move the vtn specific targets into that directory's meson.build.
