This updates the DevTools protocol to send Wiz/ACX metadata in addition to Angular metadata. Fortunately we don't need to worry about backwards compatibility here (`framework` is required for example), but the design roughly mirrors `DirectiveDebugMetadata` in `@angular/core`.
Beyond that, this is mostly plumbing through an extra data slice in the form of `props` provided by Wiz. An earlier version implemented `events` as their own slice as well, but was removed as there is currently no generic way to disambiguate events from any other form of callback passed in as a prop. Instead, event callbacks are visualized as functions under the "Props" category.
Working with `DirectiveMetadata` as a union is unfortunately a bit annoying since it requires casting to more specific `{Angular,Acx,Wiz}DirectiveMetadata` types for TS to allow property access, even when the properties are optional anyways.
This commit is mostly for adding Wiz, but does add a bit of ACX functionality which is not fully tested.

Angular DevTools
Angular DevTools is a browser DevTools extension for debugging and profiling Angular applications.
Developing Locally
Set up
Follow the instructions below to set up your Angular DevTools development
environment. Note that all commands should be executed in the repository root, not
devtools/. All file paths are also relative to the repository root.
Debian Linux, MacOS, and Windows via WSL should build successfully. Building natively on Windows without WSL is not supported at the moment.
To set up your development environment, first install the correct version of Node. If you have
nvm set up, this can be done with:
nvm install
Second, install Yarn:
npm install -g yarn@1
Third, install NPM dependencies:
yarn --frozen-lockfile
Now you should be ready to build the DevTools extension.
Dev builds
To run the extension in development mode run:
yarn devtools:devserver
You can also run a standalone version of the demo app with:
yarn devtools:devserver:demo-standalone
This would start a development server that you can access on http://localhost:4200. In development, Angular DevTools uses a "development shell." This is different from "chrome shell" in a way, that it runs the user's app in an iframe. DevTools then communicate with the user's app via message passing.
Release builds
You can build the release version of Angular DevTools for either Chrome or Firefox with:
yarn devtools:build:chrome
yarn devtools:build:firefox
Either way, the built extension will be at dist/bin/devtools/projects/shell-browser/src/prodapp.
Installation
For Chrome, you can install the extension from dist/bin/devtools/projects/shell-browser/src/prodapp by following the
guide from here.
For Firefox, to load the extension, you can go to the about:debugging page, click the "This Firefox" option and then
click the Load Temporary Add-on button. You'll have to select the manifest file in
dist/bin/devtools/projects/shell-browser/src/prodapp directly.
