BUILD files for each package have had outdated glob excludes removed.
Additionally, some src args have been reduced to a single file where possible.
The root bazel ignore file has also been expanded to include all node module
directories in each package. The ignore file does not appear to currently support
globs so each path has been individually specified.
This fixes a few error surfaced by adding `"strict": true` to `tsconfig.json`.
* `_callFs(fs.readdir, /* ... */)` needs explicit types because `fs.readdir` has a few overloads, which was confusing type inference.
* `TempScopedNodeJsSyncHost._sync` is an uninitialized property, but it was already being checked for `undefined`, so I simply made its type optional.
* `TempScopedNodeJsSyncHost.files` had an incorrect type assertion, but was otherwise correct. I just removed the assertion and let type inference do the trick.
Contains fixes related to the symlink behaviour inside of bazel. Without it, webpack needs to be configured to be aware of symlinks and preserve the paths.
Without this change, module names will be computed with incorrect paths containing duplicate path fragments (e.g. `@angular-devkit/architect/testing/testing/test-logger`).
