[feature] be able to search and identify loaded modules

**Is your feature request related to a problem? Please describe.**
Right now in order to see if modules are being loaded a common way to do this is to run

```
require.entries
```

in the chrome console. Finding specific modules would require doing something like

```
Object.keys(require.entries).filter((dep) => dep.indexOf('ember-truth-helpers') > -1);
```

**Describe the solution you'd like**
It would be great if this was exposed as a part of the ember-inspector tools as a sidebar option to see "Modules". This would allow developer to search loaded modules and also to identify potentially;

- when they were they loaded?
- what code depends on them? (in memory dependency graph)

**Describe alternatives you've considered**
Continue running this manually, it doesn't allow much granularity of what code loaded these modules or when but it works.

**Additional context**
