Ability to control log output in wit-bindgen-go

[vados-cosmonic]

Hey all, when running wit-bindgen-go I'd like the ability to be able to silence/control the output.

I'm particularly thinking about the use case of a dev tool whose output looks something like this:

starting build...
<build output, which happens to include wasm-tools-go output>
build complete
[hint] access your X at Y!

At present, the build output gets quite lengthy and would grow with the complexity of the project/amount of work wasm-tools-go is doing.

It's possible to implement suppression of output at the (higher) dev tool level, but it might be a bit more convenient if wit-bindgen-go could control logging levels and/or silence by default and let people opt in to more verbose output?

I asked around and it seems like the place to land changes would be in wit-bindgen-go -- does that sound reasonable?

I think it totally makes sense to me to add a logging control to the wit-bindgen-go cmd. We may use the log package from Go standard library. Are you interested in implementing it?

Yeah I'd be happy to work on it! Would love to hear of the idiomatic way to do it though, given the current codebase/organization -- I haven't written a large amount of Go for a while!

I think it's reasonable to move some of the output behind a -v flag.
