This commit allows building YJIT and ZJIT simultaneously, a "combo build". Previously, `./configure --enable-yjit --enable-zjit` failed. At runtime, though, only one of the two can be enabled at a time. Add a root Cargo workspace that contains both the yjit and zjit crate. The common Rust build integration mechanisms are factored out into defs/jit.mk. Combo YJIT+ZJIT dev builds are supported; if either JIT uses `--enable-*=dev`, both of them are built in dev mode. The combo build requires Cargo, but building one JIT at a time with only rustc in release build remains supported.
