[turbopack] Remove build scripts and register functions (#83156) ## What #83074 migrated us to use `inventory` for registration, this obsoleted the build scripts and `register` functions. So, delete them! ## Why? Simplification, keeping registration and definition next to each other will make it easier to maintain. I was also optimistic about build performance. unscientifically i ran `cargo clean` and then timed `pnpm turbo build-native` with and without this PR (closed VSCode and other copies of rustc) CHANGE: real 3m30.220s user 34m41.703s sys 1m44.112s HEAD: real 3m31.017s user 34m47.691s sys 1m47.096s 😢 So yeah, not much of an effect, im guessing the build.rs scripts had good parallelism in the build or were just dwarfed by wasmer
