chore(monocdk): re-do build logic (#8234)

Make the monocdk-experiment package adhere to the general flow of having
a `build` phase followed by a `package` phase, instead of doing both at
the same time.

Additionally, using a TypeScript transform to re-write imports instead
of doing search and replace. The new implementation still looks only at
the ES6-style `import`s, but could be extended to go re-write other
kinds of imports if the need arises.

This also pre-generates submodule-local configurations for naming, which
are not used right now but will become used in a future version of
`jsii`. Right now this file is just metadata.

Finally, this models the dependencies in the local package, instead of
creating a shadow package for publishing. The `yarn gen` script will
make sure `bundledDependencies`, `dependencies` and `devDependencies`
are properly configured, as well as ensure the correct `nohoist` entries
are in the workspace root's `package.json` (so the bundled dependencies
are where `npm pack` needs to have them).

+An __experiment__ to bundle all of the CDK into a single module.
 
-## TODO
+> :warning: Please don't use this module unless you are interested in providing
+> feedback about this experience.
 
-- [ ] Consider if we want core types to be available under the root namespace
-- [ ] jsii support
-- [x] Bundle all code outside of `lib`
-- [ ] Run unit tests
 
+## Usage
+
+### Installation
+To try out `monocdk-experiment` replace all references to CDK Construct
+Libraries (most `@aws-cdk/*` packages) in your `package.json` file with a single
+entrey referring to `monocdk-experiment`.
+
+You also need to add a reference to the `constructs` library, according to the
+kind of project you are developing:
+- For libraries, model the dependency under `devDependencies` **and** `peerDependencies`
+- For apps, model the dependency under `dependencies` only
+
+### Use in your code
+
+#### Classic import
+
+You can use a classic import to get access to each service namespaces:
+
+```ts
+import { core, aws_s3 as s3 } from 'monocdk-experiment';
+
+const app = new core.App();
+const stack = new core.Stack(app, 'MonoCDK-Stack');
+
+new s3.Bucket(stack, 'TestBucket');
+```
+
+#### Barrel import
+
+Alternatively, you can use "barrel" imports:
+
+```ts
+import { App, Stack } from 'monocdk-experiment';
+import { Bucket } from 'monocdk-experiment/aws-s3';
+
+const app = new App();
+const stack = new Stack(app, 'MonoCDK-Stack');
+
+new Bucket(stack, 'TestBucket');
+```
