Simplify the build by moving the generation of these files from build-time (via dgen.c that we have to compile & execute on the build system) to maintainer/release mode (via spreg-gen.py that we only ever execute when the spreg table actually changes). It speeds up the build process and makes it easier for us to reason about & review changes to the code generator. The tool is renamed from "dgen" because it's hardcoded to only generated spreg files. It isn't a generalized tool for creating lookup tables.
