Feature Request: Support optimization flags in the build actions

**Description:**
We can support several optimizations to improve the build process. This is a feature request to support optimization flags that can be passed to each build action. If an action cannot support a particular optimization, it should error out:

### Optimization 1: Use prebuilt binaries
**Benefit**: Makes build faster

When building dependencies with native modules, use pre-built binaries that are available locally or download from internet. This saves time in recompiling the same binaries over and over again. It can also make the build more stable because sometimes compilation fails or times out.

**Requested by build actions**:
1. node-npm
1. python-pip

### Optimization 2: Remove unnecessary dependencies
**Benefit**: Produces slim zips

Remove unnecessary dependency libraries, or files or folders from the output artifact. For example, remove tests, test data files, or dependencies that are already available in transitive closure.

**Requested by build actions**:
1. node-npm
1. python-pip

El issue menciona las acciones de build node-npm y python-pip, pero no indica archivos ni pruebas. Empieza por localizar las implementaciones de esas acciones y sus rutas de salida de build; después determina cómo se solicita cada optimización, cómo se rechaza cuando no es compatible y cómo se verifica en los artefactos resultantes.
