Add ability to generate combined mruby.h and mruby.c files for
single-file embedding, similar to SQLite's amalgamation.
Usage: rake amalgam
Output: build/<target>/amalgam/mruby.{h,c}
Features:
- Headers concatenated in dependency order with guards stripped
- Sources concatenated with proper ordering (core, gems, mrblib)
- X-macro headers (ops.h) inlined at each include point
- Local includes automatically inlined
- Handles both src/ and core/ gem directory conventions
