Alex Crichton 7141379559 Convert some WebAssembly run-make tests to Rust
This commit rewrites a number of `run-make` tests centered around wasm
to instead use `rmake.rs` and additionally use the `wasm32-wasip1`
target instead of `wasm32-unknown-unknown`. Testing no longer requires
Node.js and additionally uses the `wasmparser` crate from crates.io to
parse outputs and power assertions.
