Add `debug()` statements for `*.webc` files

[Zearin]

I’m brand new to WebC, and I just tested out whether I could get it to work in an existing project. I was able to get it to work with enough tinkering, but for a while I wasn’t sure if my setup was working.

Along the way I tried using DEBUG=Eleventy:WebC to see if I could get any useful output. I didn’t see anything to confirm whether my setup was having the correct effect.

It would be nice if when I do the following:

eleventyConfig.addPlugin(pluginWebc, {
        components: [
            "./_src/_includes/**/*.webc"
        ]
    })

...that a debug message would tell me that the plugin detected the *.webc files. :)

I have another request for WebC-related debug().

For each *.webc file, note whether it is being processed:

• with(out) transforms
• with(out) bundlerMode enabled
• whether the file is being processed as a layout, a page, or a component
