None of these are useful as plain strings in the templates, which forces the users to do `transform.Plainify "foo" | safeHTML`.
If people have trust issues with the output of these functions, they need to just stop using them.
Closes#8732
While very useful on its own (and combined with the passthrough render hooks), this also serves as a proof of concept of using WASI (WebAssembly System Interface) modules in Hugo.
This will be marked _experimental_ in the documentation. Not because it will be removed or changed in a dramatic way, but we need to think a little more how to best set up/configure similar services, define where these WASM files gets stored, maybe we can allow user provided WASM files plugins via Hugo Modules mounts etc.
