ATA tried to use the `_requiredBy` field to determine toplevel deps,
but this is not portable. Not only is it unavailable in npm@>=7, but
neither Yarn nor pnpm write this metadata to node_modules pkgjsons.
This also adds support for ATA acquiring types for scoped packages.

**Bug**
If the typings installer is run under a copy of node that does not include npm—but on a machine that does have npm installed—it will incorrectly try to use the npm that does not exist next to its running version of node
**Fix**
Make sure that we check that npm we select exists before trying to use it as the default. Otherwise, fall back to using plain old `npm`
* Add command line flag to gate new behavior
* Fix missing semicolon
* Rename JS concepts
1. Assignment declaration -- an assignment that is treated like a
declaration. Previously called [JS] special (assignment|declaration),
among other things.
2. Expando -- a value that can be used as a target in assignment
declarations. Currently, a class, function or empty object literal.
Functions are allowed in Typescript, too. Previously called a JS
container, JS initializer or expando object.
3. JavaScript -> Javascript. This is annoying to type, and looks like
'Java Script' in a camelCase world.
Everything is a pure rename as far as I know. The only test change is
the API baselines, which reflect the rename from SymbolFlags.JSContainer
to SymbolFlags.Assignment.
* Remove TODO
* Rename Javascript->JS
Note that this introduces a variable name collision in a couple of
places, which I resolved like this:
```ts
const isInJavascript = isInJSFile(node);
```
