Support for custom Automatic Type Acquisition scopes.

Suggestion

The ability to specify in .tsconfig and/or IDE settings additional scopes to search beyond @types for type acquisition.

Use Cases

Private repositories with large amounts of JavaScript code and a small number of TypeScript developers who wish to produce accurate typings, and a high barrier to entry to modifying/adding declaration files to the JavaScript projects. This mirrors the public ecosystem with say, react and @types/react.

Examples

A new string array parameter of scopes to search for:

{
  "typeAcquisition": {
    "searchScopes": [
      "@companyname-types",
      "@types"
    ]
  }
}

This would also allow overriding the @types scope. The first scope with a matching declaration should win.

Checklist

My suggestion meets these guidelines:
[X] This wouldn't be a breaking change in existing TypeScript / JavaScript code
[X] This wouldn't change the runtime behavior of existing JavaScript code
[X] This could be implemented without emitting different JS based on the types of the expressions
[X] This isn't a runtime feature (e.g. new expression-level syntax)

Beginne damit, die Implementierung der automatischen Typakquise und die Behandlung von typeAcquisition in tsconfig zu lokalisieren, und verfolge anschließend, wie die Scopes von Deklarationspaketen derzeit aufgelöst werden. Lege das Konfigurationsverhalten für searchScopes fest, einschließlich der Reihenfolge und der @types-Überschreibungen, und füge Tests hinzu, die zeigen, dass der erste passende Deklarations-Scope ausgewählt wird.
