Update wasm build scripts to wasi-sdk-19 and rust 1.67

[jlb6740]

Patch updates wasm build scripts to use wasi-sdk-19 or rust 1.67 and also updates the wasm files built from those scripts. The only exception is spidermonkey which failed to build regardless of sdk version. This needs more investigation.

Amazingly regex failed after upgrading to a newer version of rust due to a change in output:

     Running `target/debug/sightglass-cli benchmark --engine engines/wasmtime/libengine.so --raw --output-format csv -- benchmarks/regex/benchmark.wasm`
Error: Actual `stderr` does not match the expected `stderr`!
* Actual `stderr` is located at `stderr-1f1a1a7c163dcaf2-2151573-0.log`

So also updating the expected results file for regex.
