fix(ngcc): correctly identify the package path of secondary entry-poi…
…nts (#36249) Previously we only searched for package paths below the set of `basePaths` that were computed from the `basePath` provided to ngcc and the set of `pathMappings`. In some scenarios, such as hoisted packages, the entry-point is not within any of the `basePaths` identified above. For example: ``` project packages app node_modules app-lib (depends on lib1) node_modules lib1 (depends on lib2) node_modules lib2 (depends on lib3/entry-point) lib3 entry-point ``` When CLI is compiling `app-lib` ngcc will be given `project/packages/app/node_modules` as the `basePath. If ngcc is asked to target `lib2`, the `targetPath` will be `project/node_modules/lib1/node_modules/lib2`. Since `lib2` depends upon `lib3/entry-point`, ngcc will need to compute the package path for `project/node_modules/lib3/entry-point`. Since `project/node_modules/lib3/entry-point` is not contained in the `basePath` `project/packages/app/node_modules`, ngcc failed to compute the `packagePath` correctly, instead assuming that it was the same as the entry-point path. Now we also consider the nearest `node_modules` folder to the entry-point path as an additional `basePath`. If one is found then we use the first directory directly below that `node_modules` directory as the package path. In the case of our example this extra `basePath` would be `project/node_modules` which allows us to compute the `packagePath` of `project/node_modules/lib3`. Fixes #35747 PR Close #36249
