Expose component metadata in dev builds

[tricki]

Stencil version:

 @stencil/core@1.9.0-15 

I'm submitting a:

[ ] bug report
[x] feature request

Current behavior:
In development builds Stencil exposes data about the vdom of an element with the window.stencil.inspect method. But the data doesn't include all metadata (state variables, watchers, listeners etc.).

Expected behavior:
The full metadata of Stencil components is exposed.
It looks like the getHostRef function used in the inspect method includes this metadata (in the $cmpMeta$ property) and could be added to the global stencil object.

Steps to reproduce:
n/a

Related code:

stencil.getHostRef = getHostRef;

Other information:
There might already be a way to access this information (preferably without having to run the dev server) in which case this issue can be closed.
There is a similar issue (#1542) which would only expose the data in a separate file.
My goal is to update the Stencil Inspector Chrome Extension since it uses window.devInspector which is no longer available.

Here's an example output of getHostRef:
