This commit moves all Chrome Devtools Protocol messages to `cli/cdp.rs`
and refactors all places using these types to pull them from a common
place.
No functional changes.

This brings in [`display`](https://github.com/rgbkrk/display.js) as part
of the `Deno.jupyter` namespace.
Additionally these APIs were added:
- "Deno.jupyter.md"
- "Deno.jupyter.html"
- "Deno.jupyter.svg"
- "Deno.jupyter.format"
These APIs greatly extend capabilities of rendering output in Jupyter
notebooks.

Allows `Jupyter.display` to return a promise.
Example:
```javascript
class WikiPage {
constructor(public name) {}
async [Symbol.for("Jupyter.display")]() {
let response = await fetch("https://en.wikipedia.org/wiki/" + this.name);
return { "text/html": await response.text() }
}
}
new WikiPage("Deno_(software)")
```

This fixes #20767.
We were losing `this` and then when an exception was happening, it
didn't show up in the output because we weren't bubbling up exceptions
from within a user defined function for displaying. I thought about
doing a `.call(object)` but didn't want to get in the way of a bound
`this` that a user or library was already putting on the function.

# Implementation
Instead of going the route of recursively getting all the objects under
`application/.*json` keys, I went with `JSON.stringify`ing in denospace
then parsing it from rust. One of the key benefits of serializing and
deserializing is that non-JSON-able entries will get stripped
automatically. This also keeps the code pretty simple.
In the future we should _only_ do this for `application/.*json` keys.

"Fixes" the exception display issue of #20524 on older versions of
Jupyter that required `evalue` to be truthy. For now, until we can do
proper processing of the `ExceptionDetails` this will make Jupyter
Notebook 6.5.1 and below happy.
This is the alternative "just work now" PR to #20530

This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.
Closes https://github.com/denoland/deno/issues/13016
