fix(npm): only include top level packages in top level node_modules directory (#18824)

Browse source 
We were indeterministically including packages in the top level
`node_modules/` folder when using a local node_modules directory. This
change aligns with pnpm and only includes top level packages in this
folder. This should be faster for initializing the folder, but may
expose issues in packages that reference other packages not defined in
their dependencies. That said, the behaviour previously was previously
broken.

This has exposed a bug in the require implementation where it doesn't
find a package (which is the main underlying issue here). There is a
failing test already for this in the test suite after this change.

Closes #18822
