This PR introduces the HostBindingAdapter to utilize the functions usually available to DevTools. Additionally I moved all the DevTools related files under a `devtools` directory to better separate the extractor logic. The patch scripts for DevTools were moved under a function to remove the side-effect nature of the file. Now gets called in a the creation of the McpContext (and a before hook in test.)
