build(docs-infra): add a tool to create new examples (#39283)

This tool can be run from anywhere in the aio folder as:

```sh
yarn create-example <example-name>
```

It will create some basic scaffold files to get the example started.
After creation the developer should then use `yarn boilerplate:add`
or similar to ensure that the example can be run and tested.

You can optionally provide an absolute path to a pre-existing CLI
project and it will copy over appropriate files (ignoring boilerplate)
to the newly created example.

```sh
yarn create-example <example-name> /path/to/other/cli/project
```

Fixes #39275

PR Close #39283

 * `yarn boilerplate:add` - generate all the boilerplate code for the examples, so that they can be run locally.
 * `yarn boilerplate:add:viewengine` - same as `boilerplate:add` but also turns on `ViewEngine` (pre-Ivy) mode.
-
 * `yarn boilerplate:remove` - remove all the boilerplate code that was added via `yarn boilerplate:add`.
+* `yarn create-example` - create a new example directory containing initial source files.
