feat(npm): API facade and first compile pipeline

[ematipico]

Summary

Part of https://github.com/rome/tools/issues/3073

This PR starts works around the runtime APIs. This PR implements only few methods compared to the one proposed:

• formatFiles
• formatContent
• parseContent

The return type of these methods are not final yet and should not be part of the review. For example having content for formatFiles doesn't make sense.

What's should be reviewed should be the input types for each API.

There are some tests that will fail once we start the actual work, there's some workflow with the GitHub actions and a compilation test with just TypeScript. Not sure if we really need a bundler for now.

Test Plan

Added new tests and updated an existing workflow. The reason why I didn't add npm/rome path to the existing format workflow is because we use setup-rome, which contains the old version, while I am using the current version on main to format and check the JS code.

I will make a new PR to change that across the board, so we are able to dogfood our JS code base while we develop.
