Restructure exported package files #5151
Description
Currently, users of the monaco editor package use deep imports to access various modules, such as import * as monaco from "monaco-editor/esm/vs/editor/editor.api.js";.
Besides missing d.ts files, there is no clear difference between internal modules and API modules.
Additionally, some users want minimal monaco editor distributions where certain editor features are excluded.
The monaco editor webpack plugin allows them to configure which features are included/excluded. Alternatively, they can deep import editor.api.js and the selected features they need.
Instead, we should intentionally export modules to both distinguish between internal and exposed modules and to allow for easier configurations of "minimal" monaco editor distributions. This would be also be a first step to deprecate the webpack plugin.
The structure of the allowed imports could look like this:
import "monaco-editor"; // imports and registers everything
import * as m from "monaco-editor/editor"; // the core editor (no optional features, no languages)
import "monaco-editor/languages/register.all"; // imports all language features and definitions
import "monaco-editor/languages/definitions/register.all"; // all language definitions (syntax highlighting + bracket rules)
import "monaco-editor/languages/definitions/css/register";
import "monaco-editor/languages/definitions/cpp/register";
import "monaco-editor/languages/definitions/.../register"; // + ~50 more
import "monaco-editor/languages/features/register.all"; // all language features (autocompletion, diagnostics, etc)
import "monaco-editor/languages/features/css/register";
import "monaco-editor/languages/features/typescript/register";
import "monaco-editor/languages/features/.../register";// + ~3 more
import "monaco-editor/features/register.all"; // all editor features
import "monaco-editor/features/sectionHeaders/register";
import "monaco-editor/features/find/register";
import "monaco-editor/features/stickyScroll/register";
import "monaco-editor/features/.../register"; // + ~20 more
