Treat type and code as highlighting options in both transform.Highlight
and transform.HighlightCodeBlock. The type option overrides the language
and code overrides the code, so the two functions now share the same
options handling.
transform.Highlight's LANG argument is now optional:
transform.Highlight CODE [LANG] [OPTIONS]

Goldmark v1.8 reports source positions in render hooks.
Use this to build a source map that translates Goldmark positions back to
the original content source.
Now all render hooks' context object implenent the `BaseContext` interface:
```go
type BaseContext interface {
Position() Position
Page() any
PageInner() any
Ordinal() int
}
```

* Make throwOnError=true the new default
* Handle JS errors as part of the RPC request/response flow
* Return a new Result type with .Err on it
This enables constructs on the form:
```handlebars
{{ with transform.ToMath "c = \\foo{a^2 + b^2}" }}
{{ with .Err }}
{{ warnf "error: %s" . }}
{{ else }}
{{ . }}
{{ end }}
{{ end }}
```
Note that the new `Result` type behaves like `template.HTML` (or a string if needed) when printed, but it will panic if in a error state.
Closes#12748
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.
