Initial work on boilerplate code generator
The goal here is to get the Slang "standard library" code out of string literals and into something a bit more like an actual code file. This is handled by having a `slang-generate` tool that can translate a "template" file that mixes raw Slang code (or any language we want to generate...) with generation logic that is implemented in C++ (currently). This work isn't final by any stretch of the imagination, but it moves a lot of code and not merging it ASAP will complicate other changes. My expectation is that the generator tool will be beefed up on an as-needed basis, to get our stdlib code working. Similarly, the stdlib code does not really take advantage of the new approach as much as it could. That is something we can clean up along the way as we do modifications of the stdlib.
