Use data extensions for finding external API calls

The data extension editor was only using the default data extensions
found in the `ql` submodule to find external API calls. This will add
support for using data extensions found in the workspace.

Rather than using the `codeQL.runningQueries.useExtensionPacks` setting,
this will always include data extensions since the editor doesn't make
sense to use without data extensions. We will also forbid the user from
opening this view unless they are using a CLI which supports data
extension packs.
