feat(ivy): add support for esm2015 and esm5 in ngcc PackageParser (#25406)

Since non-flat module formats (esm2015, esm5) have different structure
than their flat counterparts (and since we are operating on JS files
inside `node_modules/`, we need to configure TS to include deeply nested
JS files (by specifying a sufficiently high `maxNodeModuleJsDepth`).

Remains to be determined if this has any (noticeable) performance
implications.
