classes/npm: refactor the npm class

This commit splits the npm build in three steps:

1. With the new npmsw fetcher, the sources and dependencies of the
   package have been fetched and unpacked. As sources can also be
   patched, a local cache must be configured to use these modified
   sources.

2. Next, the installation process is run using the local cache only.
   Some packages may need to be compiled.

3. The final installation filters the previously installed files to
   avoid unnecessary files.

This new version also fixes multiple issues related to npm dependencies
badly handled: package names, scope packages, installation directories
